青海省夏日哈木铜镍矿实物地质资料采集与保管意义初探

夏日哈木铜镍矿床是青海省第五地质矿产勘查院于2011年发现的超大型矿床,累计新增镍资源量111万吨,是全国第二大镍矿。在分析该矿床的地质背景与特征、矿床成因的基础上,结合实物地质资料的保存状况,中国地质调查局实物中心筛选采集了夏日哈木矿区的三个典型钻孔岩心及一套系列标本,这些实物地质资料将对未来东昆仑地区镍矿成矿作用及区域构造演化的研究提供重要实物依据,为进一步地质勘查提供信息服务。

Study On the Meaning of Collection and Preservation of Cores and Samples of Xiarihamu Copper-Nickel Deposit, Qinghai province

Xiarihamu copper-nickel deposit was discovered by Qinghai Geology and Mineral Exploration Institute in 2011, So far, it has become the second largest nickel deposit in China whose new nickel resources were 1.11 million tons. Based on the analysis of geological background, characteristics and genesis of the deposit, and combined with the conservation situation of physical geological data, Cores and Samples Centre of Land and Resources screened and collected 3 typical drill cores and a series of specimens of Xiarihamu copper-nickel deposit. These physical geological data can provide important physical evidence for researching on mineralization and regional tectonic evolution of nickel of east Kunlun area, and provide information service for further geological exploration.
