Summary:The plagiogranites - trondhjemite, diorite and albitite - occur as dykes, pods, and tectonic inclusions within mafic members of the ophiolite suite. They are judged to be localized, late-stage felsic differentiates of subalkaline magma. The Coolac rocks show less marked Fe-enrichment, higher Ni and Cr, and lower Y and Zr than many ophiolitic plagiogranites, consistent with a weak calc-alkaline tendency. [C.H.D.]
