On the Intrusive Suite from Biharpur, Madhya Pradesh

The intrusive suite comprises gabbro, dolerite (with hornblende-bearing variant), diorite and granitoids with both porphyritic and non-porphyritic types. A calc-alkaline character, on the acid intrusives is evident. Genetic link amongst the gabbro-dolerite-diorite intrusive members is suggested. The granitoid intrusives, on the other hand. appear to have no direct genetic lineage.
