Extremelly nice W0/1 brecciated chondrite H3.8-5/6 double shock level S2-6

Hello,

I would like to show this new meteorite, found in north Chad two years ago in the Ndrali area. Each meteorites from this fall are fabulous regmaglypted stones. Litterally a stony Sikhote-Alin. The total mass is approx 7.5 Kg. Only three little stone were cut, all others will be preserved. The eastheticals shape are too nice for cut them !!

The matrix consist in clear chondritics clast (H5/6 S2) engained in a very dark matrix (H3.8 highly shocked S6 !! ) .

The dark matrix contain many little chondrules (300 to 400 µm) flowed in chocks veins. A non negligeable part consist in primitives chondrules in wich some metal drops were found. Some of them are elliptic, partialy melt, ... There is also lot of olivines grains, some pyroxenes, chromites, PO chondrules, and type 3 chondritics conglomerates. The dark matric contain a lot of opaques inclusions.

The matrix is extremelly rich in metal flakes. They consist approx 2/3 kamacite & 1/3 taenite. Two differents taenite concentration were found, it probably come from both initial parent body.
On the base of troilite alteration study, the weathering is only W0/1.

Analysis were made during lasts months by Dransart, EMTT, Lyon, France. Several specifics mineralogicals aspects were observed by M.Denise at MHNP, Paris. This fabulous meteorite will be submit to the met bull in the next weeks under proposal name: Ndrali.

I have some slice to sale. if you are interested, you can see http://users.skynet.be/meteorite.be/ndrali.html

If you are interested by the analysis aspect, you will read the first Ndrali H3.8-5/6 mineral report within the next few days at http://users.skynet.be/meteorite.be/ndrali-analysis.html . In the next weeks, more than 50 pictures of Ndrali thin sections (chondrules, flakes, matrix, olivine cristals, chromite, pyroxenes,shock veins,..) will be added.

kind regards,
