河南省洛宁县回春沟北金矿床控矿条件初探

Preliminary exploration of ore-controlling conditions of Huichungoubei Gold Deposit in Luoning County,Henan Province

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 Deposit, introduces and analyzes the metallogenic geological background and geological characteristics of the deposit （body） , and the ore-controlling factors in the district ty and favorable tectonics are decisive ore-e are expl ontrollin ointed out that the mineral source,the magmatic aetivig factors. It is necessary to further study the space and time relation between the tectonics in mineralization stage and Yanshanian granite,and to find out the ore-conducting,ore-deposit tion and ing structures and the transportation direction and channels of ore-bearing fluids. Also,investment in deep explorashould be enlarged to find high and medium temperature hydrothermal deposits near the contact zone of granite surrounding rocks.
