三、怎样定分区名称划分构造区域,目的是为了阐明各个地区的大地构造性质及其地质发展史,以便指导找矿。因此,一个切合实际、意义明确的名称,对于任何构造区都是必需的。为了反映新近才被阐明的第三基本构造单元(地洼区)的性质,尤其需要选用一套适当的分区系统。目前中国大地构造分区名称,是比较混乱的。论其定名依据,固然有一部分是根据历史分析法定出来,足以反映一个地区的地质发展史及其现阶段
Third, how to determine the sub-area name The sub-area, the purpose is to clarify the nature of each area of the tectonic and geological history of development in order to guide the prospecting. Therefore, a realistic and meaningful name is necessary for any tectonic zone. In order to reflect the nature of the third basic tectonic unit (Diwa area), which has just been clarified, a suitable set of zoning systems should be selected in particular. At present, the name of China’s tectonic division is quite chaotic. On the basis of its name, although some are based on historical analysis statutory enough to reflect the history of geological development in a region and its present stage
