【摘要】 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。更多还原

【Abstract】 The calculated mean heat flow values of three main crustobodies in China mainland,which were deduced from abundances of uranium,thorium and potassium given by the article“ Regional element abundances of continental crustobodies in China” (Li et al.,Geotectonica et Metallogenia,1999,vol.23,101～ 107),were compared with the mean values from heat flow observations.The result shows that the calculated value is inconsistent with the constraint of observation.This fact means that the abundances of U,Th and K given by the article are too high.The author argued that the methodology used in the article does not have a reliable background in theory or experiment,which estimates the radioactive heat production elements′ abundance in crust or mantle from compositions of exposed rocks and by correlation of seismic velocity data from regional seismic profile with lithologies.Meanwhile,the abundances of other strong incompatible trace elements in the crustobodies given by the article are also unreliable.更多还原
