柬埔寨地质特征及矿产资源分布概述

OVERVIEW OF GEOLOGICAL CHARACTERISTICS AND MINERAL RESOURCE DISTRIBUTION IN CAMBODIA

柬埔寨地处特提斯成矿域与环太平洋成矿域两大成矿域交汇部位,已经发现17个矿种,其中金矿、铁矿、宝玉石及钼、锡多金属矿是四大优势矿产。洞里萨湖大断裂为界分两个大地构造单元,主要断裂为北西向、南北向、北东向和东西向四组。岩浆活动主要分近东西及北西向发育展布。北部近东西向黎府-华富里-波索竹-罗文真金、铁、铜成矿带,中东部北东向磅德拉-森莫诺隆金多金属成矿带及南部北西向难河-沙缴-贡布金、铁多金属成矿带。矿业有较大的发展空间。

Cambodia is located at the intersection of the Tethyan metallogenic district and the Pacific Rim metallogenic district.Seventeen mineral species have been discovered,among which gold,iron,gemstones,as well as molybdenum and tin polymetallic deposits are the four dominant mineral resources.The region was divided into two main geotectonic units by the Donglisahu Fault,with major faults oriented in NW,NS,NE,and EW directions.Magmatic activities weremainly distributed along near EW and NW directions.There is a nearly NWtrending Lifu-Huafuli-Bosozhu-Luowen gold,iron,and copper metallogenic belt distributedin the northern part of the area,aNE trendingPandela-Senmonolongjin gold polymetallic metallogenic belt distributed in the central and eastern parts,and aNW trending Nanhe-Shajiao-Gongbu gold and iron polymetallic metallogenic belt in the south.The mining industry has great potential for development.
