Shear-induced ringwoodite formation in the Martian shergottite Dar al Gani 670

Crystallization Experiments of Dar Al Gani Martian Meteoites: a Preliminary

Introduction: Recently, a lot of basaltic shergottites have been found from the desert areas in northern Africa and Middle East Asia. Most of them contain large olivine grains that are not present in the previously known basaltic shergottites (except for EETA79001). These olivine grains are mostly Mg-rich, but they show different mineralogical features in each meteorite. Dar al Gani 476 and its...

Sulfur Speciation in the Martian Regolith Component in Shergottite Glasses

Introduction: We have shown that Gas-Rich Impact-Melt (GRIM) glasses in Shergotty, Zagami, and EET79001 (Lith A and Lith B) contain Martian regolith components that were molten during impact and quenched into glasses in voids of host rock materials based on neutron-capture isotopes, i.e., 150 Sm excesses and 149 Sm deficits in Sm, and 80 Kr excesses produced from Br [1, 2]. These GRIM glasses a...
