The name Vaca Muerta comes from the fact that an old cattle trail crossed
the strewnfield, and many dry skeletons of cows are scattered along the trail.
The cattle came from the valleys of Salta and Jujuy, north Argentina, distant
approximately- 700 miles across the Andes. These cattle were to serve as food
for the miners of Saltpeter fields of the Atacama Desert.
The Vaca Muerta Mesosiderites were first recognized in 1861. Several large masses
up to 25 kilograms were found before 1864 and distributed to the world museums.
However, recently a new specimen was discovered after almost 100 years. Mesosiderites
are thought to have formed when a silicate rich asteroid collided at high speed with
a metal rich asteroid smashing together and mixing their contents to form this unusual
rare meteorite. Several rare eucrite achondrite type inclusions have been found inside
this meteorite and are now being studied to help understand the mysteries of its formation.
