摘　　要：通过几年的工作,棉田矿区成为重要的找矿基地。该区成矿作用主要有与华力西期闪长岩、石英闪长岩、斜长花岗岩有关的产于侵入体内及接触带型金矿、产于中、新生代断陷盆地边缘与中晚期侏罗世中酸性火山岩有关的浅成中低温热液型金矿。岩金矿床归属于吉黑褶皱系与燕山期中—酸性岩浆作用金、银、铜、铅、锌(钼)成矿系列。区域成矿地质条件十分优越。本文在分析该区成矿地质条件、矿床特征、地球化学、地球物理特征的基础上,提出了找矿方向。The work of a few years,cotton has become an important ore mining base.Mineralization in the area and the main Variscan diorite,quartz diorite,plagioclase granite intrusive body in the middle and the contact zone-type gold mine,produced in the Mesozoic and Cenozoic rift basin margin and in the late Jurassic intermediate-acidic volcanic rocks in the shallow epithermal gold deposit.Kyrgyz gold deposit attributable to the black fold system and the Yanshan period-the role of acid magmatic Au,Ag,Cu,Pb,Zn Mo mineralization series.Regional geological conditions are favorable.This paper analyzes the geological conditions of the area,deposit characteristics,geochemical,geophysical characteristics,based on the proposed prospecting.
