宾川小龙潭斑岩铜矿找矿方向思考

小龙潭近东西向核桃箐断层对岩体的控制起主导作用。核桃箐沟以北的斑岩露头总体为“模式”的外带。结合核桃箐沟断层的性质及其对地貌的影响，提出进一步找矿重点应转移至核桃箐沟南侧探寻斑岩体核部，打破在F2以北找矿的瓶颈，有望取得找中大型斑岩铜矿的突破。

THE PROSPECTING IDEA OF XIAOLONGTAN PORPHYRY CU DEPOSIT IN BINCHUAN

The main controlling factor of rock body is the nearly EW Hetaoqing fault in Xiaolongtan. The metallogenetic conditions of porphyry Cu deposit are good. The outcropping porphyry north of Hetaoqing valley is the outer zone of the ＂model＂ in general. In combination with the nature of Hetaoqing fault and the influence on geomorphology, we put forward the following suggestion, ie, the further prospecting focus must be moved to finding out the core of porphyry body on the south side of Hetaoqing valley, make a breakthrough of the prospecting idea only in the area north of F2 in order to find out the middle--large porphyry Cu deposit.
