摘要:
古巴位于加勒比板块东北缘, 矿产资源丰富, 主要矿产有镍、铬、铜、铁、锰. 其中, 镍储量占世界已探明储量的1/3左右. 2017年古巴是全球第十大镍生产国, 亦是全球第五大钴生产国. 古巴的油气储量也比较丰富. 从现有区域成矿特征及矿点分布来看, 古巴东南部的奥尔金省、格拉玛省和圣地亚哥省等地区可能是未来最有前景的镍钴矿和锰矿找矿地区; 北古巴前陆盆地及沿海、近海区是油气勘探和开发的未来突破区域. 古巴与我国关系良好, 是我国矿业公司从事海外资源开发的重要目的地. 笔者依托"一带一路"矿产资源信息采集与相关资料综合分析, 对古巴的地质、矿产及矿业开发现状进行综述, 并总结该国矿产分布规律, 为我国投资古巴矿产勘查和矿业开发提供可借鉴的建议.
Abstract:The Republic of Cuba, located in the northeastern margin of Caribbean plate, is rich in mineral resources, including nickel, chromium, copper, iron and manganese, among which, nickel reserves account for about one third of the world's proved reserves, with rich oil-gas reserves as well. In 2017, Cuba ranked the world's tenth largest producer of nickel and fifth largest producer of cobalt. According to the existing regional metallogenic characteristics and mineral distribution, the southeastern provinces of Holguin, Granma and Santiago would be the most promising areas for nickel, cobalt and manganese exploration in the future. The foreland basin of northern Cuba and nearshore zones are the future breakthrough areas for oil-gas exploration and development. Having a good relation with China, Cuba is an important destination for Chinese mining companies to engage in overseas resource development. Based on the "Belt and Road" mineral information collection, comprehensive research project data and integrated analysis of relevant data, the paper summarizes the geology, mineral resources and distributions, as well as mining development status of Cuba, which provides references for Chinese investment in mineral exploration and mining development in Cuba.
