| 摘 要： | 乌拉嘎金矿主要控矿因素是构造破碎带及裂隙带、斜长花岗斑岩体和老基底变质杂岩.其中构造破碎带是最主要控矿因素.矿化富集与含金玉髓状石英细脉或细网脉、黄铁一白铁矿脉和碳酸盐脉的发育程度密切相关.含金热液脉体的形态产状受构造破碎带和裂隙带控制，经过多期次叠加，往往造成矿化的进一步富集.矿体呈脉状、复脉状、扁豆状等形态.上述特点为该区电法找金提供了先决条件.金矿石是本区主要极化体.在乌拉嘎金矿区的张才沟靶区获得低阻高极化和高阻高极化异常，可望找到含金石英脉及含矿破碎带.

| Abstract: | The main factors of orebody controlling in Wulaga gold deposit are structure belt,fracture belt,plagioclase granitic porphyry and metamorphic rock of basement.In these factors,structure belt is the most important.The enrichment of mineralization is closely related to gold-bearing quartz veins,pyrite veins and carbonate veins.The forms of gold bearing hydrothermal veins are controlled by structure belt and fracture belt.The gold-bearing veins are superimposed repeatedly and let the mineralization more enrichment.The shapes of ore bodies are like veins and haricots.These characters provide the preconditions for induced polarization gold finding.Gold ore is the main polarization body in this area.The abnormity has been gained with low resistance and high polarization in Zhangcaigou target of Wulaga gold diggings,and it is hoped that the gold bearing veins and belts could be finded. |
