Popis: The mean U.K. heat flow is a very normal 59 mWm−2, yet the values vary systematically over the country between 40 and 100 mWm−2. There is no geological or geophysical indication that this variation is caused by recent thermal events in the mantle. A firm correlation between heat flow and ‘basement’ heat production strongly suggests that the variation originates in the upper half of the crust. Belts of higher heat flow are underlain by granite-enriched upper crust. The granite bodies are of approximately the same vertical thickness as the low-grade metamorphic rocks which they intrude: both are underlain by dense lower crust relatively depleted in heat production.
