Abstract

A xenolith composed essentially of green pyroxene, microperthitic potash felspar, sphene, apatite, and iron ore, has been discovered in the diorite of the Glenelg-Ratagain igneous complex. it is believed to be an impregnated skarn rock associated with igneous activity earlier than the intrusion of the diorite. Introduction of P, Ti, and Na is considered to be important in the formation of the skarn.
