Ordinary rock Posted July 13, 2021 Share Posted July 13, 2021 While head hunting one day I looked out and saw this dude lying ahead. I thought it looked interesting, but it stank like hell. I don't know exactly the smell to compare it too but catfish stink bait seems kinda sorta close maybe but either way it's pretty awful. I put the hole in it because I used it as a crucible one day so you can overlook that. Btw in louisiana 1 Quote Link to comment Share on other sites More sharing options...

Bedrock Bob Posted July 14, 2021 Share Posted July 14, 2021 Hematite isn't heavy nor magnetic. It is however sub metallic. And that is what it looks like in the window you cut. The cuttings were brick red weren't they? 2 Quote Link to comment Share on other sites More sharing options...

I'll have to cut it again when I get home I forgot to do a streak test And I can't remember the color of the cuttings But the first meteor wrong I ever found was hematite I believe and it was very heavy And strongly magnetic and obviously Metallic so much so I thought it was a chunk of metal for the longest. This one does have a similar look I guess but its half as dense or more and it doesn't attract a magnet except where I burnt it at around that hole. But I'll streak test it and probably get a better idea. Quote Link to comment Share on other sites More sharing options...
Bedrock Bob Posted July 15, 2021 Share Posted July 15, 2021 Hematite is usually not magnetic. But it can be sometimes. Hematite comes in all sorts of ways. As pure heavy mineral and also as a constituent in rocks. It is often sedimentary. Your rock is foliated indicating a sedimentary hematite formation. Foliation is something that meteorites don't have Streak color is everything when identifying iron minerals. Streak and luster is the only observation that is needed to differentiate (most) iron minerals that are commonly mistaken for meteorites. If it streaks in shades of red it is hematite. If it streaks in shades of grey it is magnetite. For all practical purposes that is how you tell terrestrial rocks from meteorites. Terrestrial stones have mineral iron. Meteorites have metallic iron. If you don't see free metallic iron it is simply not a meteorite. If it is not magnetic it is not a meteorite. If it streaks in shades of red or grey it is not a meteorite. 3 Quote Link to comment Share on other sites More sharing options...
Ordinary rock Posted July 15, 2021 Author Share Posted July 15, 2021 Sorry I didn't fully read your reply I guess. It isnt heavy or metallic? I was told the opposite. Your right red streak sorry for the dumb question, can't believe I forgot the streak test 1 Quote Link to comment Share on other sites More sharing options...

Your right red streak sorry for the dumb question, can't believe I forgot the streak test It can be heavy. Never metallic. Always sub-metallic... There is a difference! Iron in the form of hematite often replaces organics and other soluble minerals. A stone that is a replacement can be heavy or light depending on the amount of hematite in there. Some sedimentary hematite is as solid as it can be. That is heavier than most other rock. Some is only 25% of the total and won't make a rock seem very heavy. So it's kinda subjective. Most hematite concretions are "heavier" than they look. But the only way to really quantify "heavy" is by doing a specific gravity calculation. Meteorites leave no particular streak color. It's watery beige slurry. But oxidized iron ALWAYS leaves a streak. So any suspect rock can be eliminated fast just by rubbing it across a board with some good sandpaper glued to it. Or on ceramic. Or any other hard abrasive surface. You are looking for free metallic iron in a meteorite. Shiny steel like a knife blade. Mineral iron is sub metallic. It is grey like graphite. It is almost metallic but has a porous surface. It changes overnight to a dull smoky finish. It is a subtle difference at first. But after you rub a window in a few stones you recognize the difference. Once you master the difference between sub-metallic and metallic luster you won't wonder about so many rocks. If you ever find one with actual flakes of free metallic iron you have something. Otherwise you are looking at the various forms of terrestrial mineral iron. 2 Quote Link to comment Share on other sites More sharing options...
d_day Posted July 16, 2021 Share Posted July 16, 2021 It stinks huh? I’m wondering if you got a piece of bog iron, and the smell is what’s leftover from the fen. Quote Link to comment Share on other sites More sharing options...
Ordinary rock Posted July 17, 2021 Author Share Posted July 17, 2021 I don't know but I know it will knock you down if you heat it up it is very pungent. 1 Quote Link to comment Share on other sites More sharing options...
