.03 grams. 8 x 7 x 5 mm.   H4-5

TKW 342 grams. Observed fall 15 September 2007 in Carancas, Chucuito, Puno, Peru.

The MetBul seems to have two errors for this meteorite - the TKW and the coordinates of the fall. The MetBul puts the fall in Bolivia but other sources put it directly east of the circular marker for Reserva Aymara Lupaca and a few hundred meters inside Peru.

Not sure why the Meteoritical Bulletin is mentioned as having coordinate and TKW errors. Its 2007/8 write-up, table and coordinates in Peru look fine to me! The reason a TKW of 342 grams is mentioned is that this is what the classification group had in hand. The table in the MB mentions the TKW was possibly metric tons. But who really knows after the crazy situation that erupted following the impact... between fine powder, specimens carted off, disintegrating in the water and being buried in the soil..or squirreled away? Scientific documentation is an arduous task. Perhaps the online version could list an estimated TKW. Is it over 10kg? >100 kg? >1000 kg or more?

Gregor... I think Carancus specimens have both crust in a few rare cases, but more typically the dark material is a coating of shock material where the rock broke apart, separated, etc.

It looks alike an typical basaltic rock. Althought look acondrite (HOW) also.

The Carancas meteorite is very special. Impressive that a stone meteorite made a crater. But I read that the black material is not fusion crust but shock-venes. The clasts inside the stone broke apart through the impact.

Awesome! It's amazing how well preserved it is after such a violent impact.

This is indeed one spectacular meteorite specimen... and thanks for the MetBul corrections, too.
