摘　　要：成矿燕山中晚期花岗岩受构造、岩性联合控制,沿断裂"扎根"部位显岩舌、岩枝状产出,形成多层次凹陷,其中的锡铜多金属矿床是个旧矿区最低赋矿标高(900m),也是深部找矿的突破,从而建立深部有利部位四类成矿模式。Middle-Late Yanshanian metallogenetic granite is controlled by the structure and lithologic character together,which is tongue-like,apophyse-form at fault ＂rooting＂ place,to form the multi-level depression and Sn-Cu multimetallic deposit.It is the lowest ore-bearing level（900m）of Gejiu orefield.This is a breakthrough in deep ore prospecting,which has established the metallogenetic four models of deep advantageous place.
