DYNAMIC FORMATION AND EVOLUTION OF ORE-CONTROLLING TECTONIC SYSTEMS IN SUICHANG SILVER GOLD OREFIELD, ZHEJIANG PROVINCE

Wang Siyuan Xiao Qibing Zeng Jianguo (Faculty of Earth Resources, China University of Geosciences, Wuhan430074, China)  
The analysis of orefield structure is not only an important method for the research into the genesis of mineral deposits, the mineralization patterns, and the prospecting forecasting, but also a relatively weak part of the research into the Suichang silver gold field. In this paper, by combining the system analysis of geology mechanics with the theories and methods for plate tectonics, the authors firstly present a brief description of the geological features of the orefield, and suggest two mineralization stages in the orefield: Luliang stage and Yanshan stage. Then, the authors present a specific description of the orebodies distribution patterns in the orefield, and classify the ore controlling tectonic systems as steeply tilted folding surface system, grating overprinting and remaking system and parallel fault damaged orebody system. Finally, by identifying the plate environments of the orefield in different mineralization stages, the authors determine the regional stress fields controlling the orefield and analyze the plate driven mechanism for ore controlling tectonic systems in different stages.
