本文所称下扬子区域,系指九江以东沿江两岸各宽约30公里的长江下游地域。该区域以有大量铁、铜等金属矿床分布而早为世人所瞩目,素有下扬子金属成矿带之称。其地质研究程度也相对较高。 众所周知,六十年代以来,随着板块构造学说的兴起,地质构造研究进入了一个重大变革的时代。迄今,板块构造理论,已冲破了以往构造运动学模式的束缚,使地质构造进入了动力学研究的新阶段。 作为大陆地质构造动力学研究的一种尝试,本文在溧水、宁芜和庐枞这三个典型中生代火山岩区的地质构造研究基础上,对下杨子区域中生代以来的地质构造动力学特征试作初步探讨。
Lower Yangtze area, referred to in this article, refers to the lower reaches of the Yangtze River, each 30 kilometers wide along the banks of the east of Jiujiang. The region has a large number of iron, copper and other metal deposits distribution as early as the world’s attention, known as the lower Yangtze metal metallogenic belt said. The degree of geological research is relatively high. As we all know, since the 1960s, with the rise of plate tectonics, the study of geological formations has entered an era of major changes. So far, the plate tectonics theory has broken through the shackles of previous tectonic kinematics models and has led the geological structure into a new phase of kinetic research. As an attempt to study the geodynamic tectonics of the mainland, based on the study of the geologic tectonics of the three typical Mesozoic volcanic rocks in Lishui, Ningwu and Luzong, this paper attempts to test the geodynamic tectonics of the Lower Yangzi area since Mesozoic Preliminary discussion.
