We present the results of new EPMA studies of chromite in primitive basaltic shergottites (SAU005, EETA7001A, DAG476) and ALH84001 and Chassigny. Chromite grains from basic and ultrabasic rocks are sensitive indicators of melt compositions and the Fe3+-Cr-Al compositions of the cores can help to distinguish between partial melting and crystal-melt fractionation histories in the SNC 30 Fe3+ Chromite grains parent melts
