格陵兰岛铀矿资源潜力评价
|
摘要
格陵兰矿产资源丰富,但尚未大规模开发,现已逐渐成为矿产资源勘查与开发的热点地区。格陵兰的矿产勘查资料易于获得,但中文资料匮乏。中国铀矿类型主要有岩浆型、热液型、砂岩型和碳硅泥岩型,总体上"小、贫、散",超大型与大型铀矿床很稀缺。为缓解中国铀矿资源的紧缺状况,推动中国企业在格陵兰"走出去",在收集整理资料的基础上,初步评价了格陵兰的铀矿资源潜力。格兰陵主要的铀矿成因类型是砂岩型、砾岩型、脉型、侵入岩型、火山岩型和交代岩型6种。可确定5个找矿远景区,其中A级3个,B级和C级各1个,建议中国企业重点关注A级远景区。格陵兰政府对于铀矿开采的禁令已经解除,铀矿资源可利用性评价良好,值得中国企业关注。
Greenland is rich in mineral resources, but has not yet been developed. Greenland has gradually become a hot area for the exploitation of mineral resources. Greenland has a long history of mineral exploration and easy access to information, but Chinese references are very insufficient. The uranium deposits in China are mainly of magmatic type, hydrothermal type, sandstone type and carbon-silicon mudstone type, suggesting"small, poor and scattered"characteristics in general, and superlarge and large uranium deposits are rare. To alleviate the shortage of uranium resources in China and promote Chinese enterprises' "going out"policy in Greenland, the authors, based on the collection and translation as well as previous data, preliminarily evaluatedthe potential of uranium resources in Greenland. The results show that the six types of uranium deposits include sandstone type, conglomerate type,vein type, intrusive rock type, volcanic rock type and metasomatism rock type. The five potential areas were determined, which include three class A, one class B and one class C. The authors hold that Chinese companies should focus on class A potential areas.Greenland government's ban on uranium mining has been lifted, and the evaluation of uranium resources availability is good, which is worthy of Chinese Enterprises' attention.
