据陈国达教授创立的地洼学说,在分析和确定各铀矿床大地构造类型时,以现阶段大地构造单元的性质为准,并按其地质构造演化史,建立时空的立体大地构造成矿概念。 在划分铀矿床大地构造类型时,考虑到铀成矿作用同地壳发展的地槽、地台和地洼三个阶段有关,相应划分出地槽、地台和地洼三大铀矿床大地构造类型。再按各大地构造发展阶段内构造—岩浆活动发展程度与铀矿化关系,划分出优地槽、优地洼、渺地洼和地台等矿床大地构造区型。各种铀矿床大地构造类型中,分布着不同的铀矿床类型组合。 文中还对各种铀矿床大地构造类型的主要特征,分别作了论述。
According to Diwa theory founded by Professor Chen Guoda, in analyzing and determining the tectonic types of uranium deposits, the character of the tectonic units at the present stage shall prevail. According to the geological tectonic evolution history, a three-dimensional tectonic mineralization concept is constructed. In the classification of tectonic types of uranium deposits, taking into consideration that the uranium mineralization is related to the three stages of the earth crust, the platform and the diwa, the geotectonic types of the three major uranium deposits, . Then, according to the relationship between the degree of tectonic-magmatic activity development and uranium mineralization during the development stage of each major tectonic structure, the geotectonic zones of the Youdecao, Youdewa, Datian and other deposits are distinguished. Various types of uranium deposits in the tectonic type, the distribution of different types of uranium deposits. The paper also discusses the main features of the tectonic types of various uranium deposits.
