Unique Meteorite from Early Amazonian Mars: Water-Rich Basaltic Breccia Northwest Africa 7034.

The article discusses planetary science identifying a meteorite with a chemical composition that resembles rocks from the planet Mars' Gusev Crater. Topic include the discovery of a martian meteorite, called Northwest Africa (NWA) 7034, with a unique oxygen isotope composition, characteristics distinguishing martian meteorites from achondrites, which are meteorites resembling terrestrial basalt rocks, an analysis of NWA 7034 that revealed a greater deficiency of the 16O isotope than other martian meteorites, suggesting it may have originated from the martian crust, and a diagram illustrating how NWA 7034 may have formed on Mars.
