| 摘 要： | 本文以研究大陆板块为内容,提出了应用古基底构造来划分大陆板块的新看法。主张在研究板块水平运动时,注重于力偶转换间升降运动的研究;强调两板块间相互关系的研究。主张以活动论的观点,把有用元素的转化迁移作用,作为矿化预测的理论模式。并根据我国陆地板块及其铀矿化控矿特征,为深化研究大陆板块构造进行了初步探索。

| Abstract: | The studied contents in this paper are continental plate. According to the features of motive force when continental lithosphere and continental plates are formed, the author suggested a new view that the continental plates are divided by the paleo-basement structure.He advocates that the attention to elevation and subsidence movement during the force-even inversion and to relationship between the new and the old plates should be paid while studying the horizontal movement of the plates.In guiding to prospecting,he insists on the view of mobile theory. It is used as the theory model of prospecting for mineral deposits in terms of the transformed removal role of the useful elements among the boundaries of the different plates.
According to the features inside the plates, they may be divided into four classes the first class is continental plate,the second land plate,the third subland plate ( subplate ) and the fourth miniland plate ( miniplate ) .Each class may be divided into such structure unites as plate bodies and plate sections.
On the basis of the preliminary study of the land plates in China, the author found that in the east part there are mainly the land plates of the mobile type, in the west part there are mainly the land plates of the stable type and in the middle there are mainly the land plates of the sub-stable type. The different kinds of mineral deposits are controlled by the different land-plate types.Many uranium deposits occurred in the land plates of various ages in China, and they are controlled by the features among the specific plate boundaries and the near areas. In the light of these laws and the features of the controlled mineralization, the prospecting experiments were made, and the better effects were achieved.It is demonstrated that the detailed divisions of the land plates and applying this theoty for prospecting are of important value to both theory and practice. |
