constraints on heat production and thickness of continental plates
... The questions of continental plate thickness and radioactive heat production in the subcontinental mantle have assumed considerable significance in recent years. Jordan (1978, 1982) has proposed that continental cratons are underlain by a thick (> 150 km) chemically distinct mantle root which, toget ...
