摘要

Radiogenic heat production (RHP) in granitic rocks is a key parameter for evaluating the thermal evolution of the continental crust. This study compiles RHP data from over 14,000 granitic samples of varying emplacement ages and tectonic settings worldwide. The results show that RHP generally increases from older to younger granites, with an average value of 3.72 µW/m3. Proterozoic granites exhibit the highest RHP, reflecting enhanced crustal differentiation and tectonic activity. These findings highlight a significant correlation between emplacement age and RHP, offering valuable insights for geothermal assessments and thermal modelling of the crust across geological timescales and tectonic provinces.
