The Part Played by Tholeiitic Magma in the Carbo-Permian Vulcanicity of Central Scotland

Frederick Walker

Summary: The end-Carboniferous quartz-dolerites form a curious tholeiitic interlude in the alkaline olivine-basalt vulcanicity which characterized central Scotland from the top of the Old Red Sandstone to the Lower Permian. The relationship of the two magma-types is discussed in the light of fresh evidence.
