地洼区的过渡间成矿及其意义──以东南地洼区铀矿为例
There is a close relationship between occurrence of nonmetallic minerals and tectonic evolution of geosyncline,platform and diwa(geodepression)on the western margin of the Dongting diwa.
洞庭地洼西缘非金属矿产的产出特征与地槽、地台及地洼构造的演化具有密切的关系。
Based upon diwa metallogenetic theory,the division and evolution of geotectonic units in the province were studied in this paper,and there are 2Ⅰ class、3Ⅱ class、7Ⅲ class and 45Ⅳ class tectonic units in the whole province limits.
本文据地洼成矿理论，对省内大地构造单元的划分及演化进行了研究，将其划分为２个Ⅰ级、３个Ⅱ级、６个Ⅲ级、４５个Ⅳ级大地构造单元，认为中生代由于地台活化转入地洼阶段是省内大地构造演化的一大特点。
