江西珊城地区主要构造带特征及控岩控矿作用

通过对江西珊城多金属成矿区主要构造带的地质构造、构造岩、矿物和岩石的形变相变、构造地球化学、X光岩组及动力学分析等方面的综合研究,论述了它们的基本特征、力学性质转化及其控岩控矿作用。本文着重指出,在珊城多金属成矿区,沙坊源断裂与南瓜山-冷水坑断裂斜接构成的"入"字型构造,是该区主要的控矿构造;NNW向构造是该区重要的赋矿构造,目前探明的多金属矿体均沿此方向展布。 

ON FEATURES OF THE MAJOR TECTONIC BELTS OF THE SHANCHENG POLYMETALLIC ORE-FORMING AREA, JIANGXI PROVINCE AND THEIR CONTROL OF ROCKS AND MINERALS

A study of the major tectonic belts in the Shancheng polymetallic ore-forming area has been made mainly by an analysis of the structural features, the tectonite, the deformation and phase changes of the minerals and rocks, the tectonogeochemistry, the X-ray petrofabrics and the dynamics.The basic features of these zones, the change of their mechanical properties and their control of rocks and minerals are discussed.As a result, an ore prognosis is attempted.The authors point out that the lambda-type structure composed of the Shafangyuan fault and the Nanguashan-Lengshuikeng fault is the major ore-controlling structure and that the west-northwest structure is an important host structure in the area along which the presently explored ore bodies are distributed.
