总结了回春沟北金矿床地质找矿的阶段地质成果,对所处的成矿地质背景、矿床(体)地质特征进行了介绍和分析,探讨了本区的控矿条件. 指出矿质来源、岩浆活动、有利的构造3个因素是决定性的控制条件,加强研究成矿期构造和燕山期花岗岩的时空关系,厘清导矿、赋矿构造及含矿热液的运移方向和通道,并应加大深部找矿投入,在花岗岩与围岩接触带附近寻找中高温热液矿床.
The paper summarizes geological achievements in the prospecting phase of Huichungoubei Gold Depos-it,introduces and analyzes the metallogenic geological background and geological characteristics of the deposit(body), and the ore-controlling factors in the district are explored.It is pointed out that the mineral source,the magmatic activi-ty and favorable tectonics are decisive ore-controlling factors.It is necessary to further study the space and time rela-tion between the tectonics in mineralization stage and Yanshanian granite,and to find out the ore-conducting,ore-de-positing structures and the transportation direction and channels of ore-bearing fluids.Also,investment in deep explora-tion should be enlarged to find high and medium temperature hydrothermal deposits near the contact zone of granite and surrounding rocks.
