Structural pattern, rock and ore control and regional structural implications of the fault in the Zhaceqiao gold ore deposit in Dongzhi, Anhui
摘要
Abstract
The Zhaceqiao gold ore deposit of considerable size was found in Dongzhi County of Anhui Province in recent years. Its formation is closely related to the Yenshanian intense tectonomagmatic activities in time and space. Through gold ore exploration and special research, this paper divided major rifted structures in the area, made a systematic research into the basic features, formation and evolution, interrelation, rock andore control of observable major faults and concluded that major faults in the area formed on the basis of pre-Indosinian structures during the Indosinian and Yenshanian intense tectonic activities, and recorded Mesozoic structural transfer process at the northern fringe of the Jiangnan transition zone; the faults in the area play an important role in rock and ore control, of which the Gaodan fault controls EW tectonomagmatic rock belt, the Lanchengfan fault controls NE tectonomagmatic rock belt, ore bodies in the area are mostly controlled by O/S boundary thrusting-nappe (sliding) fault, the Huashan-Yanghu fault zone and NE fault zone, and mainly occur in the fracture zone and the secondary. It also discussed the Gaodan fault for its form of expression, formation mechanism, relation with other structures and its regional control on rock and ore, and then established formation model for major faults in the area.关键词
