一、华夏古陆的提出及岐见中国东南沿海地区的前震旦纪变质岩以往认为被泥盆系地层不整合覆盖,缺失下古生界。一九二四年葛利普首次将这一地区的古地理单位称之为“华夏古陆”,尔后为地质学者所长期沿用。一九五四年陈国达教授提出“基于这一地区系中国地台上的一个活化区,而范围又大致上相当于葛利普所早已提出的‘华夏古陆’的事实,作者建议称它为华夏活化区”。
I. Introduction and Differences of the Huaxia Ancient Lands Pre-Sinian metamorphic rocks in the southeastern coastal areas of China were previously thought to be covered by the unconformity of the Devonian strata and lacked the Lower Paleozoic. For the first time, Galip called the Paleo-Geographic Units in this area “Huaxia Ancient Lands” in 1924, and was subsequently used by geologists for a long time. In 1954, Professor Chen Guoda proposed that “based on the fact that this area is an activation zone on a Chinese platform and the range is roughly equivalent to that of the ancient Chinese land already proposed by Galip, the author suggests that it be activated by Huaxia Area”.
