摘　　要：官房白钨矿床位于云南省文山县,地处滇东南褶皱系,属于中-大型矽卡岩型白钨矿床。从矿区构造入手,对矿床的控矿构造特征及其对矿床的控制机理进行分析,研究表明,花岗岩与围岩的接触带构造是矿区成矿的重要构造因素,挤压抬升环境是成矿的基础,接触带构造与F1、F3断裂、东西向团山褶皱及围岩的层间裂隙、层间破碎带共同构成成矿构造体系。这一研究成果将对矿区进一步找矿,以及成矿规律研究提供构造方面的理论依据。The Guanfang Scheelite Deposit lies in Wenshan County,Yunnan Province,and is located at fold system in Southeastern Yunnan.It is a medium-large skarn-type scheelite deposit.In this paper,started from structures of ore field,structural characteristics of Guanfang Scheelite Deposit and its mechanism to take control of ore body are analyzed.The study indicates that the contact zone＇s structures of granite and wall rocks are important structural factors of mineralization.The extrusion and lifting environment is the foundation of mineralization.The contact zone＇s structures,F1 and F3 faults,Tuanshan fold in EW direction,interlayer cracks and interlayer fractured belt on wall rock common constitutes astructural system of mineralization.This research result will provide an important theory basis for mineralization rules and further prospecting in Guanfang Scheelite Deposit.
