Hello all,


I would like to introduce everybody a meteorite that may be the
biggest Carbonaceous CR ever found.

It was found in a margin of a lake called Marin in Uruguay
near a village called Cebollati. The meteorite was certainly
under water for some time and it may have been preserved once
Carbonaceous meteorites are very fragile.

It's meteoritics origin is evident. A slice shows very obvious
and distinct big chondrules on a dark gray matrix very caracteristic
of CR type Carbonaceous. Certainly it is the second meteorite found
in Uruguay.

Depending on the analysis result, it may be the biggest single CR
piece ever found. The biggest TWK is 114kg from Tafassasset but the
single biggest mass is around 30kg. It may also be the first CR found
in Southern Americas.

It is still under analysis and I will inform the member list the result.
