马达加斯加地质矿产概况

摘要

Madagascar is an island country,off the coast of Southeast Africa. It has favorable ore-forming geological condi-tions,and is rich in mineral resources. The country is part of the African craton,the Precambrian tectonic-metamorphic-magmatic complex cover most of the area,only in the west and the east,thers is a small amount of late Paleozoic-Mesozoic clay sandy clastic rocks-carbonate rocks and Cenozoic volcanic-sedimentary rock series. The country�s minerals are mainly distributed in the Precambrian geological bodies,while a few depositional minerals are hosted in the late Paleozoic-Ceno-zoic formation,main minerals are iron,chromium,titanium,nickel,cobalt,aluminum,gold,graphite,coal and gem etc.%马达加斯加是非洲东南部岛国，成矿地质条件有利，矿产资源丰富。该国属非洲克拉通组成部分，以前寒武纪构造-岩浆-变质杂岩为主，西部及东、西海岸带分布少量晚古生代-中生代泥砂质碎屑岩-碳酸盐岩和中新生代火山-沉积岩系。该国矿产主要分布于前寒武纪地质体中，少数沉积型矿产赋存于晚古生代-新生代地层内，主要矿产有铁、铬、钛、镍、钴、铝、金、石墨、煤及宝石等。
