Late Mesozoic high-heat-producing (HHP) and high-temperature geothermal reservoir granitoids: The most significant geothermal mechanism in South China

Differences in the geothermal regime of continental intraplate regions depend mainly on the amount and distribution of radioactive heat production in crustal rocks. Granitoids are the predominant sources of radioactive heat production and have abundant radioactive heat-producing elements, such as uranium, thorium and potassium. The Mesozoic geology of the South China Block (SCB) is characterized by long-term continental reconstruction,...
