Global Heat Flow Data Compilation and Spherical Harmonic Analysis

这笔拨款用于支持1986年底出版的热流测量全球集合的汇编和球面调和分析。最后一次全面出版的汇编是在十多年前完成的，包括大约5500个数据集，目前的数据集估计超过15,000个值，因此必须进行新的汇编和分析。热流构成地球内部最大的能量流，是预测地球外几百公里范围内温度的一级约束条件。因此，热流是全球和区域地球动力学研究、火成岩和变质岩石形成、古地磁和地质年代学、沉积诊断和油气成熟以及地球内部许多其他温度依赖或热激活过程的重要参数。

This grant supports the compilation and spherical harmonic analysis of the global ensemble of heat flow measurements published through the end of 1986. The last comprehensive published compilation was made more than a decade earlier, comprising some 5500 the present size of the data set is estimated to exceed 15,000 values, making a new compilation and analysis imperative. Heat flow constitutes the largest energy flux within the earth, and is a first order constraint in predicting temperatures within the outer few hundred kilometers of the planet. Heat flow is, therefore, an important parameter in global and regional geodynamic studies, igneous and metamorphic petrogenesis, paleomagnetism and geochronology, sedimentary diagnosis and hydrocarbon maturation, and a host of other temperature dependent or thermally activated processes within the earth.
