Chemical compositions of matrices of unequilibrated ordinary chondrites
The matrices of six unequilibrated O chondrites and one C chondrite, ALH-764 (LL3), Y-74191 (L3), ALH-77015 (L3), ALH-77033 (L3), ALH-77249 (L3), ALH-77299 (H3) and ALH-77003 (C3), were analyzed and classified into types I and II on the basis of their chemical compositions. The bulk chemical composi...
