【摘要】 本文系统阐述了亚洲中部及邻区地球动力系统的演变进程及其所制约的区域地质和成矿特征,并提出了以下新认识和新观点:①在西伯利亚陆块与中朝—塔里木陆块之间的原"古亚洲洋"区域内是全球地史演化中具有双向侧向陆缘增生与垂向增生同时发展的"双向增生"独特地区。②"古中国陆块群"是位于劳亚古陆和冈瓦纳古陆之间独立存在的古陆。由于它的特殊位置而构成了古亚洲洋与特提斯洋的"分水岭"。③地球动力学的"内动力"归根到底来自地球自身的两个方面:一是地球自转和公转形成的离心力(拉张力)与挤压力,它是地球动力学的基础,二是地球内部永不衰败的"高热能库"。当今地震、火山等等,都是地下过饱和的高热能向地表释放的一瞬间转变为强动能的地质事件。④由地球动力系统演变打造的具有不同特征的断裂系统是控矿储矿的良好空间,因此"断裂系统找矿法"是简便有效的找矿方法之一。据此提出了4个理论指导找矿的试点和验证区。更多还原

【Abstract】 This paper systematically deals with the process of geodynamic evolution in Central Asia and its adjacent areas as well as the regional geology and metallogenic characteristics conditioned by such action,and presents new cognitions and opinions as follows:① The original Paleo-Asian Ocean zone between Siberian landmass and Sino Korean-Tarim landmass is the special zone of "doubledirection accretion" which includes both double-direction side accretion and vertical accretion developed in the same time in the history of geology.② The "clustered continents of Paleo-China" are independent paleocontinents between Laurasia and Gondwanan.Due to their special location,they form the watershed between Paleo-Asian Ocean and Paleo-Terhys.③ In the final analysis,the "inter-power" of geodynamics comes from two sources:the first source is the centrifugal force(tension) and extrusion force formed by the rotation and revolution of the earth,constituting the basis of geodynamics.The second source is the eternal "high heat energy bank" in the earth’s interior.The present earthquakes and volcanic activities all result from geological events of the instantaneous change from heat to powerful kinetic energy when the ultrasaturated high heat energy is released from the earth’s surface.④ These fracture systems with different characteristics caused by the geodynamic system are good ore-controlling and ore deposition space.Hence the "mineral prediction method with fracture system" is one of the simple and effective methods.On such a basis,four test and verification zones of mineral prediction are advanced.更多还原
