摘　　要：丁钦弄银铅锌铜矿床位于金沙江断裂西侧江达火山岛弧北段。矿床赋存于花岗岩(或花岗斑岩)或火山岩与江达组大理岩接触部位,矿体主要呈似层状、透镜体状产出,属矽卡岩型矿床。各矿体受地层层位控制,丁得背斜及其内的岩浆侵入及F1、F2断层是本矿床的主要控矿构造。本文总结了该矿床的地质特征,结合地球化学成矿及成矿指示元素富集的趋势特征,得出了进一步找矿标志,对下一步找矿具有一定的指导意义。Dingqinnon silver - lead - zinc - copper depositin the west side of jinsha river fracture jiangda volcanic island arcsection. Ore deposit occurs in granite （or granite porphyry） orvolcanic rock and the Jomda group of marble contact area, Orebody is mainly a layered, lens production, belongs to skam typedeposit. The ore body under stratigraphic position control,Dingde anticline and its magma intrusion and F I, F2 fault ismain ore - controlling structure of this deposit. This paper summarizesthe geological characteristics of the deposit, in combinationwith geochemical analysis showed the trend of the mineralizationand enrichment of ore - forming indicator elements characteristics,obtained the further ore - prospecting criteria, for thenext step prospecting has a certain guiding significance.
