LuckyLundy Posted February 1, 2009 Share Posted February 1, 2009 As you know while out detecting for gold, you run across a few hot rock and they stick to my rare earth magnet. This one gave a tone on my Minelab and did stick to my magnet, but not like a chunk of steel. I took it home and scrubbed it, a little green on one of the photo's, the next with a filed window, looks like metal, and a black streak test on porcelain. What do you experts think? If not, I'll keep looking! LuckyLundy Quote Link to comment Share on other sites More sharing options...
Jayray Posted February 2, 2009 Share Posted February 2, 2009 LL, usually a black streak is Magnetite and or Hematite. There may be some streak on a weathered meteorite, but once that is gone, there should not be one. Also, other things to look for, the so called "thumb prints", a fusion crust from ablation, and chondrules. Better luck next time...

Basaltgooroo Posted February 2, 2009 Share Posted February 2, 2009 I'm sorry but that looks almost identical to my piece of hematite. [Erik] Quote Link to comment Share on other sites More sharing options...

Goldfinger Posted February 2, 2009 Share Posted February 2, 2009 You can always tell hematite from magnetite by doing a simple streak test. Hematite will give a reddish brown streak (hema=blood) Magnetite will give a real dark grey to black streak. Steve Quote Link to comment Share on other sites More sharing options...
freelancer79d Posted February 2, 2009 Share Posted February 2, 2009 I would agree with the other posts, most likey Hematite. Just keep looking and I am sure you will find one. Where do you live AZ? CA? NV? Quote Link to comment Share on other sites More sharing options...
Paleface Posted February 2, 2009 Share Posted February 2, 2009 I would agree with the other posts, most likey Hematite. Just keep looking and I am sure you will find one. Where do you live AZ? CA? NV? Actually, most likely Magnetite since the streak test was black................. Hematite will usually streak reddish brown to blood red.............
