Abstract: Herein, integrated heat production analysis in the Xiong’an area was conducted by measuring uranium, thorium, and potassium in different rock types to clarify crust heat flow contribution, simulate the conductive terrestrial heat flow, and illustrate heat source mechanisms of Xiong’an area geothermal resources. The study area was divided into three lithosphere structure types from west to east, and heat production corresponded to layer thickness and heat production with the central area having thicker crust and lower heat production than the eastern and western areas. Crustal heat production, mantle heat flow, and crust–mantle heat flow ratio reveal a ‘cold crust-hot mantle’ in the Xiong’an area.
