4.4 Billion Year Old Meteorite From Elusive Martian Crust

Research on a 4.4 billion-year-old meteorite reveals that it is a piece of the Red Planet’s crust – the first piece of its kind to reach Earth.
 
The study, which was carried out by researchers at Brown University suggests the Martian landscape is made largely of composite rocks rather than the igneous type…

The meteorite colloquially known as Black Beauty, or formally as NWA 7034, was found a few years ago in Morocco.
It is a breccia or a mix of different rock types, which have welded together in a basaltic matrix.    

Some of the components found in the meteorite match rock samples analyzed by the Mars rovers.

Spectroscopic measurements of the meteorite match the orbital measurements of the Red Planet’s dark plains – areas where the planet’s coating of red dust is thin and the crust lies exposed…

Black Beauty is illustrative of the “bulk background” of rocks on the Martian surface, Kevin Cannon, a Brown University graduate student and lead author of the new paper, said in a statement.
“This is showing that if you went to Mars and picked up a chunk of crust, you’d expect it to be heavily beat up, battered, broken apart and put back together,” Cannon said.

The research, co-authored by Jack Mustard from Brown and Carl Agee from the University of New Mexico, is published in the journal Icarus.

Analysis carried out in 2011, showed that Black Beauty was unlike any Martian meteorite ever found, most of which belong to igneous rocks made from cooled volcanic material…
