Meteorite may represent 'bulk background' of Mars' battered crust

NWA 7034, a meteorite found a few years ago in the Moroccan desert, is like no other rock ever found on Earth. It's been shown to be a 4.4 billion-year-old chunk of the Martian crust, and according to a new analysis, rocks just like it may cover vast swaths of Mars.
In a new paper, scientists report that spectroscopic measurements of the meteorite are a spot-on match with orbital measurements of the Martian dark plains, areas where the planet's coating of red dust is thin and the rocks beneath are exposed. The findings suggest that the meteorite, nicknamed Black Beauty, is representative of the "bulk background" of rocks on the Martian surface, says Kevin Cannon, a Brown University graduate student and lead author of the new paper.

Meteorite makes impression on geologists

Meteorites can be dated in the same way that rocks here on Earth can be assigned dates. From "parent/daughter" calculations we can say that NWA 7034 is about 2.1 billion years old. On Earth we geologists would call that time part of the Proterozoic Eon. "Proto" implies earlier, and "zoic" comes from the Greek for life. Life on Earth 2.1 billion years ago was quite simple, made up largely of single-celled organisms in the oceans.
On Mars, a different set of names describes time. NWA 7034 formed during what's known on the Red Planet as the Amazonian. Some 2.1 billion years ago stands near the time of linkage between an earlier wet and warm Mars and the dry and cold planet we know today.

Rock is new class of Mars meteorite

A dark lump of rock found in the Moroccan desert in 2011 is a new type of Martian meteorite, say scientists.
Weighing 320g, the stone has been given the name Northwest Africa (NWA) 7034.
