Detail of Vaca Muerta mesosiderite meteorite showing olivine and iron in brecciated fabric, Atacama Desert, N Chile.

Vaca Muerta stony iron mesosiderite meteorite, 38 mm. Atacama Desert, Chile. Found in 1861. Eucrites are believed to have come from the asteroid Vesta. Vaca Muerta is a differentiated silicate and metal rich meteorite containing many silicate and eucrite inclusions. For this meteorite to show such a varied and disrupted character, the Vaca Muerta parent body is thought to have been impacted repeatedly by different types of material to break up, mix, and fuse the various constituent components.
