 This magma produced the layered pyroxenite dunite in the ultramafic area.Thirdly there is a low titanium basalt-andesite with extreme light rare-earth element depletion that produced the layered pyroxenite-peridotite and associated gabbro cumulate.Two kinds of basalt from the Birchs Inlet–Mainwaring River Volcanics, occur in a belt north from Veridian Point and west of the south end of Birchs Inlet.
