论文部分内容阅读
读了地质论评22卷2期讨论栏内的“关于‘白沙井层’成因与时代的研究现状”一文,感到极大的兴趣。有关白沙井组(层)时代属中更新世、成因属河流相沉积的依据,除了上述文章所列出五点以外,还可以补充下列的重要论证。另外,对文章中某些论点提出商榷。 (1)在白沙井组的形成过程方面文章中仅列出了白沙井组的物质组成,而对它的形成过程没有阐明。过去主要是对它的形成过程有争论。
After reading the article “On the Cause and Epoch of Baishajing Formation” in the column of Geological Review, Volume 22, Number 2, I was greatly interested. For the Middle Paleocene Paleozoic (strata), Meso-Pleistocene, genesis is the basis of river sediments, in addition to the five points listed in the above article, you can also add the following important argument. In addition, the article discusses some of the arguments. (1) In the formation process of the Baisha Formation, only the material composition of the Baisha Formation is listed in the article, but its formation process is not clarified. In the past it was primarily a controversy over its formation.
