Geochemistry of the appinite suite
WebThe geochemistry of the late granites suggests that they formed by differentiation of a granodioritic magma resulting from assimilation of early granite by the gabbroic magma. The Wentworth plutonic complex lies on the north side of the dextral Rockland Brook fault, near the western tip of wedge-shaped basement block of the Avalon terrane. ... WebThe continental crust-like geochemistry for these maBc rocks may be achieved either by (i) as-similation of crustal rocks by asthenospheric ... compositions of the members of the appinite suite of Scotland indicate that the granites were not formed by fractional crystallization of the parental magmas of appinite suite (Rapp et al.
