坦桑尼亚金矿床地质特征及矿产投资机遇
|
摘要
坦桑尼亚金矿资源丰富,具备良好的金矿成矿条件。分析了该国金矿床地质特征,并对该国矿业投资机遇进行了阐述。研究表明:(1)该国岩金矿床主要分布于其北部的维多利亚湖东部、南部太古界绿岩带,次为该国南部及西南部的元古界乌宾迪岩系,其中,维多利亚湖东部、南部的太古界绿岩带为世界级金矿成矿带;(2)环维多利亚湖东部、南部的太古界以及卢帕金矿田、姆潘达金矿田的元古界分布区为主要的金矿产出地层;(3)主要的金矿化类型为剪切带型、石英脉型以及含金铁建造型(层控型);(4)该国地质技术力量薄弱,基础设施条件优于周边国家,与我国外交关系友好,矿业政策优惠,是我国矿业对外投资较理想的国家。
Tanzania is rich for gold resources,the gold metallogenic condition of the country is good. The geological characteristics of the gold deposits and mineral investment opportunities of the country are discussed. The study results indicated that:(1)the rock gold deposits of the country are mainly distributed in the greenstone belt of Archean strata that is located at the east and south of Victoria Lake that is distributed in the northern part of the country,it is the the famous gold metallogenic belt around the world,and secondary for Proterozoic Wubindi rock series;(2) the gold deposit occurrence strata of the country are mainly for the Archean strata that is distributed in the east and south of Victoria Lake and the Proterozoic strata distribution area in Lupa Gold Ore-field and Mpanda Gold Ore-field;(3)the main types of gold mineralization of the country are mainly for shear zone type,quartz vein type and gold and iron formation type( stratabound type);(4) the geological technical level of the country is relatively low,its infrastructure conditions is better than its neighboring countries,the diplomatic relationship between Tanzania and our country is good,besides that,the mining policy of the country is preferential,therefore,it is the ideal country for the mining investment of our country.
