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.
