Musistics Posted February 6, 2018 Share Posted February 6, 2018 (edited) Weathered suspect meteorite finds from Southern Nevada region. First two photos of possible chondrite with lavender crystals in red matrix. Other photos are green basaltic samples with pyroxene phenocrysts, traces of what looks to be pyrrhotite, and purple hue oiled. Once polished, there is evidence of oxidized iron and possibly olivine? Other classifications? Eucrite, weathered Pallasite, SNC meteorite? Note: All samples magnetic, no streak, weathered fusion crust and flowlines, Metal Detector picks up traces of Fe (Iron). Density tests not performed. Edited February 6, 2018 by Musistics Added more photos. Quote Link to comment Share on other sites More sharing options...
Morlock Posted February 6, 2018 Share Posted February 6, 2018 Meteorites don't have vesicles so that rules out the last two pics. The others look suspect as well. Quote Link to comment Share on other sites More sharing options...
Musistics Posted February 6, 2018 Author Share Posted February 6, 2018 Thanks for the quick reply. Had tough time uploading images in order. The vesicled samples where solid and slightly pitted when sliced. Quote Link to comment Share on other sites More sharing options...
Mikestang Posted February 6, 2018 Share Posted February 6, 2018 (edited) None of them appear to be meteorites to me, all look terrestrial. First one shows quartz clearly and no evidence of being chondritic. Edited February 6, 2018 by Mikestang Quote Link to comment Share on other sites More sharing options...
billpeters Posted February 6, 2018 Share Posted February 6, 2018 The vesicled ones are basaltic, terrestrial. Most of the rest are doubtful. The ones with seeming metal flecks are intriguing. All would need a first hand look. billpeters Quote Link to comment Share on other sites More sharing options...
Rocky Posted February 6, 2018 Share Posted February 6, 2018 Just out of curiosity was this Stone wet in the picture and can you please take a close up of the sawn polished face with the margins included. I think I see a profile along the margin but there are lathes as well so I really would like to see a better shot of this one. Quote Link to comment Share on other sites More sharing options...
Rocky Posted February 6, 2018 Share Posted February 6, 2018 I had a terrestrial rock just like this with staining similar to yours and Im curious to see the margin of the cut I hope you don't mind, they all appear to be terrestrial. 1 Quote Link to comment Share on other sites More sharing options...
Rocky Posted February 6, 2018 Share Posted February 6, 2018 (edited) This one is actually appearing this way because the reflection of light off the smooth areas and the direction the camera is pointed, if you look to the right of the rock you can see polished smooth areas on that side as well that appear grey as the rest of the rock just polished so the areas that seem to look almost metallic is due to the light source shinned directly on it and if the light was just ambient rather than direct it would look uniform to the color of the stones similar polished surfaces on the right. That is not metal it is literally the white light shinning off the polished surfaces imo. Edited February 7, 2018 by Rocky Quote Link to comment Share on other sites More sharing options...
Musistics Posted February 7, 2018 Author Share Posted February 7, 2018 Hello everyone. Thanks for the feedback. I’ll check my photo library for more pics. My rocks are in storage but I have some sample pieces I can photograph and upload to site. Stay tuned... Quote Link to comment Share on other sites More sharing options...

Musistics Posted February 7, 2018 Author Share Posted February 7, 2018 Sorry for the poor photos. Used LED Flash on iPhone. Please bear with me, I’m new here.

Rocky Posted February 7, 2018 Share Posted February 7, 2018 Yeah the best bet at this point is to having these rocks looked at it in the Rocks and minerals forum, they could give you the better answers maybe you'll be happier with, like Bill said they are nice photos so that will help for identification purposes. Be prepared to perform some tests in some instances. It looks like you have collected terrestrial rock that all vary from the three main groups igneous, sedimentary, and metamorphic. 1 Quote Link to comment Share on other sites More sharing options...

billpeters Posted February 7, 2018 Share Posted February 7, 2018 Musistics, Take a look at your rock(s). If it glistens like a crystal structure (ie: quartz) at any point in the rock it can’t be a meteorite. If it has layers, it can’t be a meteorite, it’s sedimentary. If it has small gas bubbles in it, it can’t be a meteorite. It’s basalt. If it is moderately magnetic it is not a meteorite. If there is a thick crust on it, it can’t be a meteorite. File off a corner or cut it. It won’t diminish its value. If there is all bright silvery metal it can’t be a meteorite. If it is all grey metal it can’t be a meteorite. If there is black crust as thin as a fingernail, and crazing on the outside of the rock, it might be a meteorite. If there are small silver specks visible in the filed off section, it might be meteorite. There are billions of magnetic rocks in the US, none of which are meteorites. Anyone can find magnetic earth stones nearly everywhere. Just take a strong magnet and drop into sand and you will see what I mean. Check our O Richard Norton’s, “Rocks from Space” or visit the Arizona State Un. Meteorite Center or other similar facility. billpeters P.S.

fredmason Posted February 8, 2018 Share Posted February 8, 2018 P.S. It seems like I repost this every other week. and that is because it is easier to ask first and research later...just a little effort on the enquirer's part would be nice... fred 1 Quote Link to comment Share on other sites More sharing options...
Jayray Posted February 11, 2018 Share Posted February 11, 2018 Bill, I would have to disagree with some of the statements, ie magnetic, sure they can. Irorns are magnetic, and there are some that are all grey as well. H-metal fits that category. A meteorite can also have a thick crust but more rare then the common chondrite. I will agree though that what I see in the pic do not look like meteorites IMO either. But what do I know, I’ve been know to be wrong before. Keep looking down...

billpeters Posted February 11, 2018 Share Posted February 11, 2018 Jayray, My post lists standard characteristics of typical meteorites. Of course there are exceptions for nearly everything I've written, but I'm educating the general uniformed public who thinks just because their rock is magnetic it must be a meteorite. It is important to cut through standard misconceptions and give a basic guideline as to what to look for in typical meteorites versus the meteor-wrongs. Your pics pretty well match what are not meteor-wrongs and show what are meteorites. Keep looking down, billpeters Quote Link to comment Share on other sites More sharing options...
