ABOUT NWA 7397 MARS Meteorite
Mass: 2.1 Kilo
Purchased: 2012 Jun
Classification: Martian meteorite (Shergottite)
History: Found near Smara, Morocco and purchased by Darryl Pitt and David Gheesling from a dealer in Zagora, Morocco in 2012 June.
Physical characteristics: A 2130 g (2.13 Kilo), partially covered in fusion crust. Interior larger ovoid crystals in a finer grained matrix.
Petrography: (A. Irving and S. Kuehner, UWS) Large oikocrysts (up to 1.5 cm across) of low-Ca pyroxene enclose multiple chadacrysts of olivine and Cr-rich chromite. Relatively equigranular domains between oikocrysts are composed of low-Ca and high-Ca pyroxene (showing very limited compositional zoning), maskleynite and olivine with accessory merrillite, Ti-chromite, pyrrhotite and ilmenite (with associated grains of baddeleyite up to 10 μm across). Olivine contains sparse melt inclusions composed of K-Na-Al-Si-rich glass surrounded by characteristic post-shock radial expansion microfractures.
Geochemistry: Olivine (Fa38.9-40.7; FeO/MnO = 47-54), orthopyroxene (Fs30.3Wo3.3; FeO/MnO = 36), pigeonite (Fs25.1-27.6Wo6.6-10.0; FeO/MnO = 28-33), subcalcic augite (Fs17.0-19.0Wo35.1-35.4; FeO/MnO = 22-25). Bulk trace element composition (G. Chen, UAb): analysis by ICP-MS of clean wire-saw cutting dust gave (in ppm) La 1.66, Ce 4.48, Nd 2.93, Sm 1.13, Eu 0.3, Gd 1.59, Dy 1.95, Yb 1.02, Lu 0.14, Hf 1.66, Th 1.15, Rb 2.89, Sr 33.6.
Classification: Martian (shergottite, poikilitic).
Specimens: A total of 20 g of type material and one large polished thin section are on deposit at UWB. The main mass is held jointly by DPitt and D. Gheesling.
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, after Mercury. Named after the Roman god of war, it is often referred to as the "Red Planet" because the iron oxide prevalent on its surface gives it areddish appearance. Mars is a terrestrial planetwith a thin atmosphere, having surface features reminiscent both of the impact craters of the Moonand the valleys, deserts, and polar ice caps of Earth.
The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the largest volcano and second-highest known mountain in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos andDeimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Mars trojan.
