We investigate the 2D thermal structure of lithosphere in the Central Asian and Pacific tectonic belts and adjacent cratonic areas of Siberia and North China using a synthesis of geothermal data from six geoscience transects covered by seismic, resistivity, and gravity surveys. The patterns of rock density, radiogenic heat production derived from U and Th abundances, thermal conductivity, temperatures, and respective heat flows reveal a layered structure. The model with layers distinguished according to density and thermal parameters includes well pronounced dome-shaped features in the crust which correlate with upwarps of the asthenospheric top. The domes are marked by high heat flows of 60-90 mW/m(2) with a mantle component higher than the crustal one (30-60 mW/m(2) against 20-30 mW/m(2)) and temperatures as high as 800-1100 C at the Moho. Many of these features correspond to known and potential petroleum basins. (C) 2009, IGM, Siberian Branch of the RAS. Published by Elsevier B. V. All rights reserved.
