摘要

花岗岩放射成因产热是评价大陆地壳热演化的一个重要参数。本研究汇编了来自世界各地不同侵位年龄和构造背景的14000多个花岗岩样本的RHP数据。结果表明：RHP总体上由老向新花岗岩增大，平均为3.72µW/m3；元古代花岗岩的RHP最高，反映了地壳分异和构造活动的增强。这些发现强调了侵位年龄与RHP之间的重要相关性，为跨地质时间尺度和构造省份的地壳地热评估和热建模提供了有价值的见解。

A review on heat production data in granites across the world: an insight for geological setting and emplacement age

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.
