长江中下游转换构造结的特征、属性及其研究意义

FEATURES, ATTRIBUTES AND RESEARCH IMPLICATIONS OF TRANSFER STRUCTURE KNOTS ALONG THE MIDDLE-LOWER YANGTZE RIVER REACHES

"长江中下游转换构造结"是特提斯构造体制与太平洋构造体制交汇、衔接和转换的焦点部位,主要包括大别造山带、郯庐断裂带、长江中下游成矿带三大著名的构造单元,是中国东部中新生代大陆动力学深部过程与浅表响应的经典地区。将大陆造山带、大型断层、矿集区结合起来,瞄准板内变形、运动学和动力学,建立区内大陆动力学的系统研究框架,研究两大构造体制转换的精细过程,分析陆内构造演化和动力学的深部过程与浅部效应,将有助于大陆动力学理论的新突破,指导"第二成矿空间"的深部找矿。

The transfer structure knots along the middle-lower Yangtze River reaches are the focal points where the Tethys tectonic mechanism meets,links up and transforms with the Pacific tectonic mechanism,substantially including the Dabie Orogen,Tan-Lu Fault and Middle-lower Yangtze metallogenic belts,referred to as three major well-known tectonic units,which are typical of deep-seated process and surface response of eastern China mid-Cenozoic continental dynamics.It will greatly favour new breakthrough in continental dynamic theory and guide deep-seated ore prospecting in ＂second metallogenic space＂ to combine continental orogen,large faults and mining camp,aim at intra-plate deformation,kinetics and dynamics,build up systematic research frame for continental dynamics in the area,study the delicate transformation process between two major tectonic mechanisms,and analyze the deep process and shallow effect of intra-continental tectonic evolution and dynamics..
