摘要:

印度金矿类型主要有4种:绿岩型、砾岩型、砂金及伴生金矿,具有分布广、相对集中、规模小、品位低及埋深较大等特点。绿岩型金矿是印度最重要的金矿类型,集中分布在南印度克拉通和印度中央克拉通的前寒武系绿岩带中。南部东塔尔瓦尔克拉通的科拉尔金矿和胡蒂金矿是典型的绿岩型金矿,其中,科拉尔金矿金平均品位为16 g/t,黄金储量>1 000 t,属于超大型金矿床;胡蒂金矿金平均品位为4.85 g/t,黄金储量>150 t,属于大型金矿床。印度金矿探明储量十分有限,但大量较小规模金矿广泛分布在印度克拉通绿岩带,预示印度金矿具有很好的资源潜力。增加印度金矿勘探和开发投入,将发现更多具有重要价值的金矿资源,也可能彻底改变印度金矿的现状。

Abstract:

India’s gold mine has four basic types:greenstone belt type,conglomerate-type,alluvial gold mine and associated gold mine.India’s gold mine has a feature of wide distribution,relative concentration,less large and rich mineral deposits,and the great depth and so on.Greenstone type gold mine which is the most important gold type in India,concentrates Precambrian greenstone belt in South India craton and central India craton.Kolar gold mine and Hutii gold mine in the East of Darwar craton in south India are typical greenstone type gold mines. Kolar gold mine is a super-giant gold deposit with an average gold grade of 16 g/t,and gold reserves > 1 000 t;Hutti gold mine is a large gold deposit with an average grade of 4.85 g/t,and gold reserves >150 t.The proved reserves of India’s gold mine is very limited,but a lot of smaller gold deposits are widely distributed in India craton greenstone belts,which indicates there is a very good potential of gold resource.Increasing the investment in the exploration and development of India’s gold mine will make more gold resources with great value be discovered and may also completely change the status quo of India gold.

Key words: gold mine, geological characteristic, craton, greenstone belt, India
