老挝北部华潘省(Houaphanh)华芒(Houamuang)铁矿床地质特征及找矿标志

Geological characteristics and prospecting clues of Houamuang iron deposit in Houaphanh of north Laos

老挝是我国近年来国外风险勘查重点支持的东南亚国家之一。通过路线地质调查、磁法剖面测量和槽探等勘查工作,在华潘省华芒县发现了一个优质富铁矿床,暂且称之为"华芒铁矿床"。本文着重从地层、构造、岩浆岩等三个方面与成矿的关系,阐述了华芒铁矿床地质特征及找矿标志,为后续找矿指明了方向。

In recent years,the People＇s Republic of Laos has become one of the Southeast Asian countries which are fully supported by China＇s＂risks detection of the foreign mineral resources＂project.Through the route geological survey,magnetic profile survey and trenching works,a high-quality iron-rich ore deposit is found in Houamuang County of Houaphanh Province,and it is called＂Houamuang iron deposit＂temporarily.This paper started with an analysis on the relationship of mineralization with strata,structure and magmatic rocks.Then it summarized the geological characteristics and prospecting clues of Houamuang iron deposit,and proposed the direction for subsequent prospecting works.
