摘要
应用地球动力学分析结合岩石圈演化历史分析法的原则,提出动力构造分析的观点,对全球构造活化的成因类型、基本特征、分布规律以及成矿作用进行研究,并据此观点对地壳构造单元的更替递进的多向演化模式进行探讨。
Using the analytic method of geohistory and geodynamic, sthis paper studies the global activatory types and their evolution. The author is of the opinion that the activatory types are related to the gcodynamic environment. According to the tensional spreading(including shear)and compressive converging of the lithospheric plates and other various dynamic environments, the Diwas on the Earth can be divided into tensional and compressive series totaling nine activatory types and a number of subtypes. The regularity of origintaion and evolution of Diwas are similar to those of Oceans. The sequence is continental rift system type, intercontinental type, Atlantic margin type, Pacific margin type,epeiric island arc and epeiric sea type, circum-Himalaya type. They represent the six stages of Diwas evolution which are infancy, child, mature, old and dying stage respectively. Based on the above opinion, the author proposes a new model of poly-element and poly-direction evolution and substituting progression of gcotectonic elements of the Earth crust. The various types of Diwa's metallization are related to the geodynamic environment. So each type not only has its special metallization iclated to its own environment but also may inherit the compound 01 multiple mineral deposits of its predecessors, which shows the richness and variety of the metalization of Diwa.
