我国金矿床实物地质资料保管体系建设

The System for Preservation of Real Geological Data of Gold Deposits in China

金矿床实物地质资料保管实施应考虑到确定采集目的、制定金矿床目录的筛选条件、制定矿床内实物地质资料保管规范、实施实物地质资料采集等四个方面,其中制定金矿床目录筛选条件和矿床内实物地质资料保管规范是重点。金矿床目录筛选条件包括空间分布、矿床类型、矿床规模、成矿时代、找矿热点区。根据该筛选条件国家实物地质资料馆在全国范围内确定了30个代表性金矿床作为保管对象。实物地质资料包括实物(岩心、标本、光薄片及相关副样)及相关资料(与实物密切相关的成果资料、原始资料及影像资料等),其收集保管应具有系统化、规范化的特点,以使实物地质资料的价值最大限度地发挥。

Identifying collecting aim, working out catalogue filtering condition of gold deposits and specification of real geological data in deposits, implementing the collection of data are the four constituents that we must take into consideration in preservation real geological data of gold deposits. Especially, we should attach more attention to working out catalogue filtering condition of gold deposits and specification of real geological data in deposits. Specifically, the catalogue filtering condition of gold deposits covers a range of spatial distribution, deposit type and scale, mineralization age, and the hotspot of prospecting. In accordance with this filtering condition, 30 typical gold deposits have been determined by National Geological Cores and Samples Library as objects preserved on a national scale. Real geological data means the cores, samples, polished thin section and related duplicate samples; along with achievement materials, original sources and video images which is closely related to the real objects. In addition, its collection and preservation must be in accordance with systematization and standards with a view to maximizing the value of real geological materials that contribute to the society.
