摘要
云南省德钦县拖顶铜多金属矿床,区域构造上位于松潘-甘孜褶皱系中甸褶皱带之东旺-巨甸褶皱束。控制矿床的地质因素包括成矿构造、岩浆岩、地层、岩相古地理、后期保存条件等,该矿床铜矿体的赋存与地质构造密切有关,矿区丰富的断层、裂隙、节理不仅为矿源提供富集空间,并且为后期的富化创造良好条件,而成矿物质的来源则与地层的沉积密切相关。
Regional structure of copper polymetallic ore deposit of Tuoding in Deqin of Yunnan, is located at Dongwang-judian folded strata belt of Zhongdian fold zone in Songpan-ganzi fold system. There are the ore-controlling factors including ore-forming structure, magmatic rock, stratum, lithofacies paleogeography and later preservation condition and so on. The ore-hosting space of copper ore deposits is closely related to the geologic structure, there are the plentiful faults, fractures and joints in the deposit area, which provide not only the concentrating space, but also ambient conditions for later period enrichment. Therefore, there is the closely relationship between the ore-forming material recourses are and the stratigraphic deposition.
