The Guanfang tungsten deposit is located in the South China plate and Yangtze plate contact area, southeastern Yunnan fold belt Wenshan - Funing faultfold of the beam, thin the Chushan arch fold the southwestern margin of the deposit is a magmatic - mesothermal contact metasomatic tungsten deposits. Kunming University of Science and Technology in 2009 for the implementation of the the Wenshan Guanfang mine lead and zinc the tungsten ore exploration project, the construction of 22 boreholes expose the granite and skarn zone skarn zone containing tungsten ore body, the ore was infested like distribution in the rock. In this paper, the analysis and summary of previous work on the basis of the results, through in-depth and detailed geological investigation, collected a large number of geological information, starting from the regional geological background and the geological study of mine stratigraphy, tectonics, igneous rocks The mineralization relationships were studies and research focusing on the structure of the contact zone mineralization characteristics. From both the macro and micro aspects of the evolution and change of the mining structure analysis, to demonstrate the Guanfang mine temporal relationships between structure and mineralization; geological characteristics and Mission Hill ore block wall rock alteration and mineralization law summary of the the official room Tungsten Deposits law, and various structural ore-controlling factors, mine ore - controlling model. Through the study of mine ore-controlling structure characteristics and formation mechanism draw the structure of the granite wall rock contact zone is the Guanfang metallogenic important factors. Contact with tectonic Mission Hill the anticline, Shinzo anticline and peri BEDDING fissure strata constitute the hydrothermal circulation system. Mission Hill anticline, Guanfang anticline and surrounded strata of layered fracture mineralization former structure, is the main ore-mine host structures, constructed of granite and country rock contact zone mineralization tectonic ore fluid migration space of the channel and ore occurrence, a strong the contact sector with its nearby wall rock alteration and mineralization obvious, its shape determines the shape of the orebody. East-west fault and north east trending fault structure mineralization period, mineralization ore-controlling structure and the ore body from the damaging effects. Mine wall rock alteration is strongly the alteration zoning obvious According alteration of lithofacies and rock chemical test results, combined with drilling catalog information on Mission Hill ore block wall rock alteration zonation, summed up the the alteration zones in the rock component migration characteristics obtained diopside - tremolite alteration with tungsten mineralization main enrichment site. Through systematic analysis of the Guanfang mine tectonic evolution and mineralization structure at the same time, the generals the Housing mine ore-controlling structure formation and evolution summed up the ore-controlling structure mode.
