利用低温热年代学数据计算造山带剥露速率时需要考虑热流、地形、放射性物质的生热等因素,因此近20年来发展起诸多计算方法,包括矿物对法、年龄高程法、Turcotte法、Stüwe法、Mancktelow法、谱分析法、有限元三维模拟等。其中,当地温场处于稳态时,对于钻井或垂直剖面连续采样可采用年龄高程法,对于二维有周期性地形可采用Turcotte法、Stüwe法、Mancktelow法,对于二维非周期性地形可采用谱分析法,有限元三维模拟适合于求取区域剥露速率。

When calculating the exhumation rates of orogenic belts, some factors should be considered including heat advection, topography, radiogenic heat production, etc. As a result, many methods have been developed in the recent two decades, including the age-elevation relationship, the Turcotte's, the Stüwe's, the Mancktelow's, the spectral analysis, the finite element analysis method, etc. When the geothermal field is in a steady state, age-elevation relationship is applicable to the consecutive sampling of vertical section. The methods of the Turcotte's, the Stüwe's, and the Mancktelow's are applicable to the 2-D periodic topography. The spectral analysis is applicable to the 2-D non-periodic topography. And the finite element analysis is applicable to the calculation of regional exhumation rates.
