Nantan Meteorites

[Beeper Bob 91]

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

Sorry, but those look like meteorwrongs.

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

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.

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.

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. Thank you, Bob

Hi Steve, I will have my brother do a streak test. Thank you Bob

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.

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:

I am sure they are not Nantan meteorite，they are iron mineral from Guangxi province，China。

Real Nantan is like this。
