This is a very nice piece of the Vaca Muerta meteorite. It is classified as a stony-iron, mesosiderite, sub group A1. The total known weight TKW is 3,828 kg approx.. Mesosiderites are formed on the surface of a parent body when an other one impacts, and broken fragments of surface eucrite get mixed with olivine and iron from deep within the body. It is assumed that the eucrites have come from the asteroid Vesta. The Vaca Muerta mesosiderite is slitely shocked S1 and has generally a very weathered exterior. Even though, it shows lots of metal inside and often an interesting breccication.
