摘要
三个井矿区位于额济纳旗-大兴安岭一带铜、铅、锌、金、银、铬、铌成矿区和额济纳-雅干华力西期铁、金、铜、钼、镍成矿带上;也是在北山成矿远景区黄砬子-三个井金多金属成矿带上.地质条件较好,构造复杂,岩浆岩活动频繁,本文重点分析三个井铅金矿地质特征,初步圈定8条铅金矿体,总结了矿床成因类型及找矿标志.
Abstract
Three mining areas are located in the copper,lead,zinc,gold,silver,chromium,and niobium mineralization areas in the Ejina Banner Daxing'anling area,as well as in the Ejina Yagan Hualixi iron,gold,copper,molybdenum,and nickel mineralization belt;It is also located in the Huanglazi Sangejing gold polymetallic mineralization belt in the Beishan ore-forming prospect area.The geological conditions are good,the structure is complex,and the activity of igneous rocks is frequent.This article focuses on analyzing the geological characteristics of three well lead gold deposits,preliminarily delineating 8 lead gold ore bodies,summarizing the genetic types of deposits and prospecting indicators.
