Beeper Bob Posted August 31, 2007 Share Posted August 31, 2007 Hi Everyone, My brother purchased these meteorites recently. They are from the Nantan Fall of 1516. The small one is 867 grams and the larger one is 3,918 grams. Both for $120.00. He would like to know if there is any way to polish or wire brush the smaller one to bring out the iron highlights (maybe spray polyurathane on it for a protectant?). Any help would be appreciated. Thank you, Bob Quote Link to comment Share on other sites More sharing options...
Mr Hunter Man Posted September 3, 2007 Share Posted September 3, 2007 Sorry, but those look like meteorwrongs. Joe K Quote Link to comment Share on other sites More sharing options...
Kaimi Posted September 3, 2007 Share Posted September 3, 2007 I would cut a "window" on the side of them just to be able to show the inner contents. But other than that I would leave them alone. Aloha for now, Stan aka Kaimi Quote Link to comment Share on other sites More sharing options...
John B. Posted September 3, 2007 Share Posted September 3, 2007 Hi Guys I have a piece of nantan that's been sealed in something :confused0013: ?? I think the picture on the left is a magnatite nodule and not a space rock :Huh_anim]: . The pix on the right could be a piece of nantan :shrug: . I've seen table fulls of magnatite nuggets bieng sold as nantans at the Tucson Gem and Mineral show :POsmiley01: !! When you tell the table person he's selling leaverites they always act stupid !! Most of the real pieces are badly deteriorating at a fast rate :PO2: !! Similar to the lowland campos :Huh_anim]: !! Happy Huntin John B.

Goldfinger Posted September 3, 2007 Share Posted September 3, 2007 Bob: You can check to see if both of them are magnetite by doing a streak test. Find a piece of unglazed white porclean tile and rub the specimen across the face of it. If you have a black streak- chances are it's magnetite.

Beeper Bob Posted September 3, 2007 Author Share Posted September 3, 2007 Hi John B, You are probably right. I have some magnatite nuggets from Utah and they do look the same. I will tell him to check them better. It is interesting about the Tucson show that could be where they originally came from.

Basaltgooroo Posted September 4, 2007 Share Posted September 4, 2007 i have some nantans that have the characteristics of nantans but are oxidized all the way through and are "terrestrialized" and i think the one on the left is just a low grade nantan that someone polished up.

[Erik] If that's the case,you might get a reddish brown streak indicating an oxidized meteorite. If you get a black streak- it's probably magnetite. :twocents: :twocents: I'm not totally convinced you can "oxidize" an iron meteorite all the way through without it falling apart but then I'm no expert either. I've read many accounts of these so called Nantans are actually hematite,magnetite,etc. I'm sure you've heard in the news about how China is the worlds leading producer of fakes. Seems like it may have spread into the field of meteorites . :grrr01: :shrug: Steve Quote Link to comment Share on other sites More sharing options...

Thank you, Bob I am sure they are not Nantan meteorite，they are iron mineral from Guangxi province，China。 Real Nantan is like this。 Quote Link to comment Share on other sites More sharing options...
