  1. Yes! There are two ways to get the answers to your questions. The scientific way... Get them classified and have someone who is experienced in marketing meteorites give you their opinion on value. The other way... Call them "rare carboniferous chondruloids from Uranus" and convince someone they are worth $40 per gram. Just pick the one that suits your business style and go for it! I would call the first one basalt with some sweet inclusions. You could easily get $5 for that rock at the Farmers and Crafts market. I would call the second one a piece of bronze that has been tumbled into a blob. It might be worth a dime in metals value. Those are just my opinions though and I know nothing about rocks, meteorites or the value of either.

    Natural placer platinum is generally alloyed with some iron. So it will react to a magnet when you wave it under the pan. The only two elements that mercury will not amalgamate with is platinum and iron. So if you clean your material up with a little solvent like acetone and then a strong basic solution you can see that it has no affinity for mercury by putting a tiny drop in the pan and trying to coax the particles together. Most platinum is tiny "color" and you are going to have a tough time getting an XRF gun to hit on it. If you have a lump of it you might have some luck otherwise it is a lot like identifying little particles of gold. I generally use the appearance, weight (how it acts in the pan), slight magnetism, and no affinity for mercury after a good cleaning to identify platinum. If your material shows these characteristics then simply have a sample assayed to tell you for sure. Ask the assayer what test would be best. Sometimes AA or GCMS is best and sometimes fire and ICP is best for certain elements. Tell them your interest is platinum so they can recommend the appropriate analysis rather than making assumptions yourself and requesting a specific test.

    A few oddities

    Here are three interesting things found on a recent trip to the diamond fields just east of Lake Deming. A carving of a bear that must be mighty old. A fossilized core of a seashell and a petrified prospector's pucker.

    The "battle" covered a lot of ground for several days between the villages of Rowe and Canoncito on both sides of the pass. There are two recognized "battlefields" that are monuments and several private ranches figured into the equation too. No doubt there was action on NF land somewhere. All that NF land is heavily wooded foothills on the flank of Glorieta peak or way up on top of Glorieta Mesa. There is precious little NF land that an army could maneuver horses, cannons and stuff on. Out there in the NF land in heavy woods with steep slopes would be a poor place to be and it is my guess there was very little fighting on what is now NF land. The battle happened on what is now downtown Pecos and the Glorieta residential lots and small ranches. I am not sure what difference the land status makes. You could not legally hunt artifacts on NF land any more than on the monuments. And it is not difficult to access private land where you could hunt them. As a matter of fact there is private land and a shrine to the battle just off the highway in the pass where you could access one of the main battlefields. A fellow named Al Sanchez owned it and he encouraged guys to hunt there. Al is passed and the status of that land may be different now, but to the best of my knowledge you can still hunt there. There is a cannon sticking out of a gravel bench on Al's property. You can walk down a trail and down the creek a bit and take a peek at it. Lots of other neat finds made there too. There is (was) a "caretaker" that lived there and would tell the stories to anyone who would listen. Since the battle covered many miles there is lots of opportunities to hunt on corporate, state and other "non residential" private land with little consequence. And then there are several big private ranches where a fellow could easily get permission to hunt. NF land, monument land, and private land with no permission is the land you CANT hunt civil war artifacts on. But that represents only a small fraction of the potential battlefield. There are several big pueblo complexes that are cultural sites and a whole bunch of historic buildings that would be off limits too. The battlefield is not the big hunt there. Nor is the meteorite. This area is the Santa Fe trail and where the Spanish taxed the wagons. It is where the Comanche fought the Spanish and then served as their security. It was the place where the Genizaros became farmers and blacksmiths and created the first Spanish colonies. It was where the cowboys drove the cattle to load them on the train. There are silver coins, religious artifacts and Milagros buried on every peak and under every tree. There are old graves, descansos, moradas and ancient villages everywhere. Old outposts, Spanish pajares and cowboy camps everywhere. Railroad artifacts and wagon train stuff. Route 66 sites with hundreds of old filling stations and tourist trap sites. Then there is Santa Fe itself which is an urban treasure hunter's dream. That is where the diamonds are at! There is so much good stuff to be found around here it is amazing. And the possibilities for getting an exclusive on a good dig is real. Meteorites not so much.

    You might find slag around the railroad, an old mining operation or somewhere they were welding but I am talking about just bits of torn metal. You find lots of pieces of metal in the woods. Mostly chunks of striking tools, axes and splitting wedges. Chain links, points of tools, teeth from trenchers, metal from vehicles, etc. etc. Anywhere around Santa Fe you have the old trails, the railroad, the highway, and all the wood cutting, farming and ranching operations. Then there was a running battle there that lasted several days and covered many square miles of mountains. Lots of schrapnel was produced. So you hit a lot of little chunks of tramp metal without much form. Some are broken and twisted from the original piece and some are just rusted away to formless blobs. All of that is suspect meteorites before you finally find one. Then all of that goes in the trash and you can settle down to the business at hand.

    It would be cool to locate that acre and recover one of those gems just for the sake of the hunt. It would be a great treasure hunt IMHO. Very few could say they found one of those gems. It seems the collectors value may be far greater than any value the stone(s) might have as a gem. It would sure make a great treasure story...

    I love carnelian agate. I have seen huge slabs of that pretty stuff from Oregon! I always wanted to go hunt some there. I saw a YouTube where they were picking up big palm sized sabs of the stuff that looked like pink ribbon candy. They were somewhere in a volcanic field in western Oregon. Hey Birdbrain! Have you ever hunted for Oregon carnelian? That very first photo is getting darn close.

    Here are some small Glorietas for you to compare yours with. If you find anything that looks like this I owe you some beers. I honestly hope you cash in on that offer.

    Tramp metal of some sort. Free metallic iron can only be tramp metal or a meteorite. Those are the only two choices that are possible. His is some type of metal artifact.

    It just does not look anything like a Glorieta. They are not hard to identify. Even the little tiny ones. Glorieta has a black/blue crust and is very sculpted. The rust is thin and several shades darker than terrestrial trash. Not bright like your piece. It is generally not corroded too badly and never has a shaley exterior like yours with little granules of sand stuck to the corrosion. If you see granules involved they are little shards of olivine. It is rounded, smooth, hard and heavy. And the smaller the pieces the more rounded little blebs and drops they are. They just don't look like tramp metal at all. They look more like blued BBs with irregular shapes. I have found a semi truck full of tramp metal and every piece looks like yours. I have found a shoe box full of Glorieta and not a single piece looks like yours. That coupled with the fact that the odds of you finding one without knowing exactly where to look are almost zero. That is what makes me sure. This is just my opinion though and the best explanation that I can offer you. If SEM tells you this matches the metallurgical profile of Glorieta then you can wave it in the air and proclaim that you have found one. I'm sure not going to argue with you and I will still buy you that beer. But you will have a hard time convincing anyone who is familiar with Glorieta because it just does not look anything like the material I have found or seen.

    It sure does not look like a meteorite. Maybe a sandstone concretion of some sort. You are looking for metal flakes or chondrules in the window. I don't see any. Sorry man, I don't think so. But you did the appropriate test to find out! Now go find one that does stick to a magnet and has iron flecks inside! Regards, Bob

    Once you have had the experiences that we have had then you will understand the humor. I hate to tell you but your specimen is not a Glorieta. You asked for an inroad to Glorieta and I gave you sound advice instead. I'm sorry it was not what you wanted or expected. But it is as good as you are going to get. The shortest route to success in this hobby is the route I laid out in my post. It is the shortest route to Glorieta as well although not a direct one. That is just the way it is. If you want to scour the ground in the NF somewhere for a Glorieta you can do that but I can assure you it will only make you see the humor in our posts more clearly. It will not, however yield any meteorites. If ever you decide to actually locate and hunt a strewn field and learn a bit about meteorites then feel free to ask. Glorieta is the only one you will not be able to find cooperation on. This isn't about you my friend. Please don't take it personally. Post your finds and if you do find one on NF land I will drive up to Albucrazy and buy you a drink. Heck I will buy you six. You will have earned them! Good luck Mr. Ice.

    That was a piezo spark. Notice it will jump across an air gap. Now rationalize. If that spark will jump across an air gap could it run across a (barely) conductive surface? Could the spark be travelling across the surface of the stone rather than through a conductive center? Now ask yourself, "are the conclusions I reached from my observation based on assumptions?" Then try the same experiment with a boiled egg and see if you get the same results. Then consider the fact that only iron meteorites would be conductive anyway. The vast majority of meteorites would not be conductive. So a conductivity test would not really tell us much even if we performed it correctly. So we must seriously ponder our methodology before we proceed lest we waste time and arrive at the wrong conclusions. After all this is an experiment. May I suggest a definitive experiment you can do to determine if your stone is from space? I would suggest that any suspect stone needs to have a window filed in it. Use a piece of 80 grit sandpaper with some water on a plastic cutting board to grind a small window. Sand off one of those protrusions on the side. Make sure to get down into the stone and get past any weathering or cortex on the outside of the stone. Now smooth that surface with 120 grit and note the color of the slurry. That is the "streak". A meteorite will leave a clear, whitish paste that has no real color. Hematite will leave a streak with red hues from bright red enchilada sauce to dark auburn but it will be red. The window will reveal the inside matrix of the stone and it will be easy to identify. If it is a meteorite it will have chondrules and metal flecks inside. If it is an earthly rock you will see familiar earthly minerals. Post some photos of your experiment and show us the results!

    This is a piece of opalized wood. It is not a mineral. It formed from an organic material. I was just trying to identify this specimen and was not making sweeping claims that all opal was formed from organics. It was just a generalization. My post was written to help the fellow who posted the stone understand a bit about his specimen. It was not meant to be a comprehensive dissertation on every possible environment that opal could form in.
  19. Look on the bright side Clay. At least it isn't fossilized aboriginal art burri burri stones with lights in the trees wanting to kill you. So chin up lil' buddy! Spring will be here soon and we can hunt for soft diamonds at Kilbourne hole under the shade of the carved Spanish poodles. I hear a meteorite caused a brush fire out there and cleared a bunch of new ground. The soft diamonds are so magnetic that you just swing a horseshoe around and they pop up through the sand like melon sprouts. We will hire undocumented Spanish masons to mine them for us and spend the rest of our days choking the chorizo and smoking the kimberlite pipe.

    Wood can be agatized or opalized. The opal wood has a chalkier cortex and is a bit more brittle. Yours looks like classic opalized wood or bone. So I am going on looks alone (all I've got is a photo bro ). Opal is glassier and softer than agate but is made from the same elements. You can tell it is a bit softer by breaking little pieces off the specimen and comparing that to another piece of wood agate. Opal is not really a mineral per se. It started as organic material. It did not form in the way a mineral does. This piece was formed as a plant (or animal). Vein opal was formed from an organic rich solution. Opal is organic material that has been silicified. So I don't think it is really considered a mineral. Petrified stuff is in a limbo of sorts between the plant and mineral worlds. Stuff like opal, jet and amber are different than minerals. They are wood, bone and sap that have undergone some big changes. Corpralites (crap agates) would share a spot on the same shelf.

    So I thought this was cool!

    That is opalized wood and the clear portions are clear opal. It could be bone. It's hard to tell.
  22. Cataclysmic activity with plasma bursts and electrostatic air are the perfect environment to form common opal.

    Is this Agate?
