hi every body did i find a meteorite ?


Recommended Posts

hi everybody i'm a knife maker - construction worker i'm working in spokane wa, for the month and brought my whites MXT with me to cover the off time maybe find some gold or a meteorite i'm going to north dakota next week to finish out the work year before winter.... i think i found one its about the size of a quarter, heavy ,and it sticks to a magnet its got some rust color outer layer on some of it and looks like a rock "i know its not just a rusty bolt" so either its a meteorite or a good fake LOL i found it in spokane WA. on this construction job i'm working yesterday i have pic's but photoshop isn't working for me right now ... i'll try to get a pic.. up maybe someone can help me tell if it is or not.....my mxt sounded off iron and its heavy for its size the guy at the rock shop said its looks like one to him but he don't know because he's never seen a real one before so he was not help .and after driving across town the guy at the detector shop was closed even though his sign said he was sapost to be open i might of stayed around some but with the camper on the truck and all my good stuff inside i didn't even want to leave to go in the shop it's not the best part of town in fact real bad part by the looks of it thank god i was armed or i might not of even stopped . just saying it might of been just fine but didn't look that way. my MXT read -37--42 iron in relic mode and 90 per.iron in prospecting with the same -42 reading you can't tell by the pic's but theres some darkness to the stone but because of the weather here in spokane snow rain and time i don't know what that does to a meteorite i'll see if the pic's work ... also i found one other on the same job site but aways away and smaller what do you think

Clint love to know

RIDDLE me this ironarmknifes, WHY are the pics with the sample in the plastic bag "in focus" and the ones out of the bag out of focus ????

Makes looking at your find pretty tough why don't you try it again out of the bag from a few different sides of the sample.

Could possibly be an old weathered Chondrite. Did you find it in a wash? Some of the pictures look like Gold Basin meteorites. Cut a window into it and look for shiny metal flakes.

Have you done a streak test on it? From looking at your photos, I would say no, because it appears to have gas bubble areas in it ... But it could be a really old chondrite that would give it that weathered appearance ... Do a streak and a window on it to know more ... Cheers, Unc

ya i'll have to look into a window test and streak test i'll read some and how to do them and get back to ya... and where dirt movers on this construction site just big equipment no one has small tools LOL up close it doesn't look like gas bubbles more like old rust but what do i know LOL thats why i'm here to learn ...... i'll look into this window and streak test stuff.... after work today...

You can use a common file to expose the interior in an area of the stone.. Just keep the file stationary on a surface and hold the sample in your hand while rubbing back an forth untill you get thru the surface to see the interior.

Its funny one of the 1st pics in the plastic bag gave the appearance of a common chondrite with what seemed to show some remnants of black (fusion crust) and also possible raised areas like chondruls. But your 2nd set of pics doesn't.

The last pic in the 2nd set shows a totally flat side on the left of the stone , that would be a perfect place to start the filing to expose inside.

This pic isn't the greatest but you can get the idea of seeing the shining reflective spots these are nickle and you may see a similar interior in yours.

They will look like bits of chrome plated pieces of metal.

ok got my knife stone and worked on this some with my magnify glass i can see some flakes of something but i need to polish it some more to get a real look what do u think i know its hard to see from these pic's i might just be seeing hope with my mag glass we'll see when i polish it some more .... if you all think its worth it ....

THATS NOT FLECKS, its solid metal you are seeing similar to an old rusted piece of iron.

Judging from the previous pics especially the one with the flat edge showing I would gander a guess that its not a meteorite but it is a piece of scrap metal from years ago.

I haven't seen any iron meteorites with a flat side or surface on them but I'm not an eggspert either, So you might want to have it analyzed at a lab to be sure.

If you think you found a meteorite REV 12

If you think you have found a meteorite and are looking for help identifying, there are a number of steps I recommend you take before you start sending pictures and such to people that might know. Note that none of these tests prove a meteorite.

The tests, should they prove positive, indicate you have a candidate specimen that might be a meteorite.

My suggestions below were born by my experience and are intended to help you prior to bothering any one that you might consider an expert.

Note that any one of the tests below are in no way conclusive in the identification of a meteorite. Collectively, if all of these tests are performed and the results are positive, it only tells you that you might have a meteorite. At that point in time, after the tests have been performed and show positive results, then go bug an expert.

How you found the meteorite is a good way to help start the process. A meteorite found with a metal detector will normally sound off. A hunter will know they have found something special. However, rocks known as hot rocks will also sound off a detector.

Pictures – IMPORTANT

I put pictures at the top of this page because more than not people take lousy pictures that do no one any good. Everyone gets excited when they think they have found a meteorite. It’s understandable. One of the first things that seems to happen is the finder will immediately send out pictures of the rock asking people if they think it’s a meteorite, without any clue as what is needed to determine if it is a meteorite. Pictures are more than often useless, because they are out of focus, do not show a quality view of any kind and do not show a quality view of the inside of the stone…a picture of the windowed area. Remember, we are trying to help you. We need quality close up pictures to see the details needed.

A note about pictures. Please do not waste anyone’s time taking pictures with a cell phone.

Most professional investigators do not want pictures with cameras under 7 megapixels. When you take the picture, place something of known size in the picture along with the rock. A penny, nickel, dime or quarter, for example. The camera should have and be in the macro mode for close ups. A close up is generally no further away than 5 inches from the specimen. Also, take the pictures in natural sunlight. DO NOT use zoom. Most people are not set up to take good indoor pictures. Before sending the pictures triple check it and insure it is in focus. Do not send pictures that are out of focus. Take your time and do your best. If you take lousy pictures, find someone else to take the picture!

To review taking pictures:

  • Outdoor natural lighting.
  • Camera 7 megapixels or higher
  • Macro (close up) mode. And if you have it, anti-shake mode
  • Put something next to the rock for size comparison.
  • Don’t send pictures that are out of focus! Check them.
  • Do not use zoom.

Magnetic - Most all meteorites are magnetic. The first step is to determine if the specimen is magnetic. Many earth rocks are magnetic and some are more magnetic than typical ordinary chondrites. This single test in NOT conclusive but is a step in the right direction. All meteorites I have found are magnetic.

Also note that pure hematite is basically not magnetic. The attraction to a magnet is very weak. Magnetite (Fe3O4) is extremely magnetic.

Look and Feel – Often, rocks are found that are very magnetic and have holes in them. Looking at these holes, they look like the rock boiled at one time and gas was escaping from them making holes all over them. Baking a cake is probably a good example. It looks like a bunch of bubbles popped and left holes in the process. These are not meteorites. Every person that has held my meteorites can tell me that they feel heavy and solid for their size. It is an obvious immediate feeling. Meteorites are usually dense, more so relative to earth rocks of the same size. There is absolutely no specific size or shape to a meteorite. It could be a whole piece or a broken part. Visit my web site as well as others[1] and view the videos[2] and pictures and read to gain knowledge. The IMCA has pictures of classified authenticated meteorites. Look! Read! Do the research. Don’t expect others to do this for you.

You need to look at the rock under magnification. A x10 or better loupe is a good way to go. When you do this, you can really see better detail. You can easily see earth rock characteristics, such as pin sized holes. You can easily see something that looked like metal to the naked eye is only the crystal content reflection. This look is really a pass-go. If you see pin holes or the metal appearance seems to disappear under magnification, it’s pretty much done at this point…it’s got a 99.9999% chance of not being a meteorite.

WindowFor me, this is the must do step. Earlier, I mentioned the 10x loupe. Really, any kind of 10x magnification will work. You must see inside a meteorite to determine the structure.

Shinny metallic flecks: Care should be taken to distinguish between true metallic grains and certain glittering crystals or flecks of minerals such as mica or pyrites or quartz, etc. Normally, with some experience and the 10x magnification, one can easily see the differences by rolling the sample around in light to view it at different angles. If you still can not distinguish the metallic grains, you can take a hard sharp needle and by prodding while looking under magnification, you can see if it crumbles or is ductile. The Nickle-Iron is very ductile and will not crumble.

As you have looked at my videos as well as others, you have seen the internal structure. Does your rock have this structure? Do you see the shinny metal flakes? Do you see chondrules (spheres)? Do you see pin holes? If you see shinny metal flakes about 1mm in size (or smaller) sprinkled around in the window, Super!! If you see chondrules or little round objects, Super!!

Take your time with this and think about it. It is not necessary to cut a rock in half to create a window. Just look at the rock and find a spot on it that is already a little flat. File or grind or sand this area smooth and only deep enough to get past the outer part of the rock. It normally will take a diamond file to do this. A high speed grinder with a cut-off wheel will do the job. Be safe and do not squish the rock in a vise….that is a big no-no! If you file it or grind it, the view becomes better if you sand it with something like 200 to 600 grit wet/dry sandpaper. Note, for pictures, when you complete your window it will be smooth, like a polished surface. If it is not smooth, take the time to make it that way.

image001.jpgimage002.jpg

At this point, if these tests above prove positive, you are in good shape. Honestly, this might be the time to consider showing this rock to an expert or a hunter that has experience with meteorites. Not all people with detectors are experts and most do not hunt meteorites. And trust me, every “expert” was at the point you are right now at some time in their past. Some of them have forgotten this.

Strike (Streak of the mineral) Test - There is one more test you can perform easily. This is a good diagnostic test for mineral ID so you can do this to rule out an earth rock such as hematite or magnetite, wad, etc. These rocks are oxides and will leave a specific streak. They are normally dense rocks and are often mistaken for meteorites. You need a piece of unglazed ceramic (non-colored) in order to perform this test. Find a coffee cup. On the bottom of a coffee cup, there is normally a ring (where the cup sits on a surface) that is not glazed. Take your specimen and where you made this window (assuming you have a smooth surface) rub it on this unglazed ceramic. You do the streak test in the window area you made to eliminate the chance of any surface decay or terrestrial contaminants affecting the color. Did it leave a streak? If it is a rusty reddish streak, it’s likely Hematite (Fe2O3). Hematite is a light to dark gray rock, often black when whole. A greenish black streak might mean pyrite.

If it’s a grayish to black streak it’s likely Magnetite. However, I want to point out that a meteorite sitting on earth for many years “might” show a slight streak for a number of reasons. This one test by itself is not conclusive in my opinion.

If no streak at all, this is a very good sign.

Nickel Test – This is a favorite test for meteorites for me. The search for nickel! Most all meteorites contain an amount of Nickel in them. It is not common for an earth rock to contain nickel at the levels contained in meteorites. While there are chemical tests that can be performed, they are destructive tests. And, many people do not do this well and these tests are known to give false positives. I am really talking about these allergy test kits people used to determine if something they may wear has nickel it, like a ring or necklace. An old school lab nickel test is normally where you take a small sample of the specimen (if a stony meteorite) crushing it finely in a mortar. Then you boil that in diluted nitric acid for about two minutes and let it cool. Once cooled, you would add ammonium hydroxide to render it alkaline. You would then filter it and treat the filtrate with a few drops of dimethylglyoxime and if nickel is present the result will be a bright pink color. This even works for a very small amount of nickel. It is because of this small amount of nickel that renders this test inconclusive. If positive, it is a step in the right direction, but not everything that is needed to be known. And, unless you are trained at handling chemicals properly, I highly recommend staying away from chemical testing of any kind…period!

XRF testing is becoming common place and non-destructive. I recommend this. I offer this service for anyone who wants a Go / No-go test to determine nickel test. XRF stands for Xray Fluorescence and is a non-destructive elemental analysis technique. Without going into any real detail, atoms react when radiated. They become ionized.

Energy is an effect and each element responds differently. These differences can be measured.

This is how I test for nickel. The report returned to the client is a good document to provide when one is trying to have a meteorite classified. It does give hope to the scientist that they are not wasting their time and is a clean professional approach for pre-classification work for a field engineer. Contact me if you would like this done with your specimen.

So if everything is positive, it is time to contact an expert or experienced hunter. In your report, include the test results you performed above…all of them. Explain your test. Just do not say that you “performed all the tests”. Explain the tests you performed because “performed all the tests” really means nothing. I can help with all pre-classification work and possibly find a classifier.

As a final comment. In 1942, H.H. Nininger once wrote, “It is a job for an expert in the study of these bodies. In fact, the beginner should never be satisfied with his own judgment on any specimen until it has been verified by a specialist, because once a mistake is made and not corrected it continues to be the cause of mistakes on the part of other persons who see the specimen.”

If this page helped you or you have a suggestion to make it better, or want me to look at your rock please contact me and let me know.

Yes Jim very nice post.

But unfortunately people are people.

And theres not much you can do to change that fact.

I kinda believe thats one of the main reasons this forum is here.

As time takes its toll on the people that contribute to it others will replace them to offer a word of advice and or encourgement on posted questions.

When it comes to space rocks yes their are times when you, I and others can look at one and say/know yes thats a meteorite.

But untill it is run thru a lab theres no definitive verdict on it. Most of us know that but thats not what the posters are after.

They are looking for instant gratification thats why they post.

So its up to guys like you an me an many others that have learned from others before us and also field experience to get em started in the right direction.

Believe it or not there aren't alot of people out there in the general public that know what most of us know. OR know as much as some of us do about gold and meteorites.

I guess what I'm saying is yeah the pointers and guidlines in the IF YOU THINK YOU FOUND A METEORITE REV 12 are great to have for anyone to view that has a suspect space rock.

BUT like I said people are people and they just kinda want some feedback from others thats why they post I guess.

Keep on Beepin my friends. Hapy Huntn.

ya what frank said , you know i make knives and started making knives threw reading and talking to people on forums like this one and every time i made something like a knife there where people to help some people to say good job and some that just say why don't yo know it all you should of read this or that ,but i was after the friends part of the whole thing also the people that would tell you the truth but have fun doing it ... as soon as i polished the stone today i was let down .... dang it i just knew that it was just iron of some type but i still think it looks like a rock to me.... i make damascus steel some 5000 layer knives so i burn steel at 2300 der. and pound on it move it and work alot with it. and after polishing this rock meteor wrong LOL i new it didn't have the out of this world steel look it still might be something wears that i don't know the name of it just looks to much like a rock to be just some old iron LOL LOL ...so i'll keep trying even thow going out and looking will be harder the next time knowing i didn't find one.....LOL so what i'm saying is thank you for helping me along this road and i'll keep coming back because i have found gold nuggets with my whites MXT and i will find more fun stuff and so far this site has been the nicer i have looked at .. ova and if i was at home i might of broke out the canon 20d and shot pic's of the rocks wannabe meteorites in my photo booth but my iPhone has a 8 i say 8 mega pixel camera and it was what i had at the time so thank for all the help and fun guys i'll have this looked at when i get home threw the kids microscope hell i can't even see my own fingers without glasses any more you never know..... but i think after polishing it i think its just iron ...... thanks just a pic of one of my knives to show i too know steel just not your world but some day i might get lucky and find one of these meteorites......LOL

Absolutely beautiful work Clint.

I hope you find an iron meteorite one day thats big enough to fashion a blade from because it would make one hell of a piece.

Keep on beepin :thumbsupanim

I have a friend who did just that and what a blade i'll see if i can find it. and show you. and yes some day i will find my own this guy who made this blade was given his meteorite i want to find my own.this man is just the best when it comes to people he's a great family guy and has all ways helped me and yes this is a meteorite knife you should see how he made it . lots of time and fire .....

Hi Frank,

My post was in response to yours, suggesting he google some info. So, I just brought some of the info here! Good seeing you yesterday!

Hi Jeff,

I tend to be at Franconia alot! So, I assume you mean for the October outing and I will likely be there.

Jim
