Introduction: The Martian meteorite North West inserted into the furnaces (note that rhenium was used Africa 6162 (NWA 6162) is a shergottite found in Mo- instead of platinum to decrease the probability that the rocco in 2010. Only one abstract is published about charge will experience Fe loss). Charges were NWA 6162. It discusses the bulk composition of the quenched in water (excluding NWA 5) at the end of meteorite and the composition of the olivine cores and the run. They were then cast in epoxy, cut and po- rims. The meteorite bears olivine crystals with Mg- lished. depleted rims of up to Fo65.1 and more Mg-rich cores of The Cameca SX100 electron probe microanalyser up to Fo74.1 [1].
