| Abstract |
The paper presents summarized heat flow data obtained from more than 217 heat flow stations over East Siberia and Mongolia. On the most of the area the heat flow varies from 30 to 50 The highest flux is observed in the Baikal rift zone. Heat production of rocks varies from about 0.59 to 5.7 Heat flow /heat production correlation relationships established for the rift zone and south-eastern Trans-Baikal area did not prove valid for Mongolia. The lithospheric,thickness from geothermal data is 200 km beneath the Siberian platform thinning to 150-170km beneath the Trans-Baikalarea, and to 55-75km under the Baikal rift zone. |
