本文作者据《中国大陆壳体的区域元素丰度》一文给出的壳体放射性生热元素铀、钍、钾的丰度,计算出中国大陆三个主要壳体的平均热流值,将其与实测大地热流平均值进行对比。结果表明计算值不满足实测大地热流值的约束,这意味着该文给出的铀、钍、钾的丰度值偏高。我们认为,根据区域地震剖面地震波速推断岩性,再利用出露地表的相应岩石的成分估计地壳或地幔放射性生热元素丰度的方法,缺乏十分可靠的理论或实验基础。同时该文给出的中国大陆壳体的其他强不相容元素的丰度值是否可靠也值得商榷。
According to the abundance of uranium, thorium and potassium in the shells, which is given by the article “Regional Elemental Abundance of the Chinese Continental Enclosure,” the author calculated the average heat flow values of the three main shells in mainland China and compared them with Measured the average value of the heat flow compared. The results show that the calculated value does not satisfy the constraint of the observed geothermal heat value, which means that the abundance value of uranium, thorium and potassium given in this paper is high. We believe that there is no solid theoretical or experimental basis for estimating lithology based on the seismic velocity of regional seismic profiles and using the composition of corresponding rocks exposed from the surface to estimate the abundance of radioactive heat elements in the crust or mantle. At the same time, it is debatable whether the abundance values of other strongly incompatible elements in the Chinese mainland shell are reliable.
