1区域地质背景研究区大地构造位于“杨子准地台”的西部,处于“川滇南北向构造带”与四川盆地“新华夏系沉降带”的交接地带。西邻康滇地轴,东接四川台坳,西北侧相邻龙门山、大巴山台缘断褶带。区域构造发育,以褶皱为主,岩浆活动不频繁,主要出露侏罗系中统、三叠系、二叠系及泥盆系地层。区内铜矿产地分布较为集中,主要分布在昭觉县乌坡向斜四周,美姑县东部以及东南部区域,按
1 Regional Geological Background The tectonic framework of the study area is located in the western part of the “Yangzi Prospect Platform” and is at the junction of the “Southeastern Sichuan-Yunnan tectonic belt” and the “Sichuan Basin” “Xinhua-China subsidence belt”. West of Kang Dian axis, the east of Sichuan Tai Au, northwest side of the adjacent Longmen Mountain, Daba Mountain edge margin fold belt. The regional tectonic development is mainly fold-fold with less magmatic activity, mainly exposing to the Middle Jurassic, Triassic, Permian and Devonian strata. The distribution of copper deposits in the area is more concentrated, mainly distributed around the slope of Wupo in Zhaojue County, eastern and southeastern part of Meigu County,
