我国金矿资源分布特征及国家级实物地质资料筛选

Distribution Characteristics and Screening of Gold National-class Physical Geological Data of the Gold Mineral Resources in China

金矿是我国重要的战略矿种之一,在全国范围内均有分布,矿床类型以绿岩带型、浅变质碎屑岩型及卡林型为主,集中分布于胶东、华北地台南缘、西秦岭、东秦岭、辽东、滇黔桂、哀牢山等9个成矿带中,青海、新疆地区金矿资源潜力巨大,是未来找矿重点。在分析我国金矿资源分布特征的基础上,认为国家实物地质资料馆金矿资源实物地质资料筛选应考虑金矿床成矿规模、矿床类型、成矿区(带)、成矿时代等因素,可将具有典型性、潜力巨大的金矿床作为筛选对象。上述研究成果对于我国金矿资源勘探找矿、资源开发利用有一定的参考价值。

Gold resources is one of the most important strategic minerals in our country,it is distributed extensively on a national scale in our country. The gold deposits are mainly of greenstone formation type,shallow metamorphic clastic rock type and micro-granular disseminated type in genesis,they are mainly distributed in nine areas such as Jiaodong,southern edge of north China platform,western Qinling,eastern Qinling,eastern Liaoning province,the triangle area of Guizhou-Guangxi-Yunnan and Ailaoshan etc. The gold resources potential in Qinghai-Xinjiang area is great,so it is an important ore prospecting area in the future. Based on analyzing the distribution characteristics of the gold resources in our country,the factors of the screening of gold national-class physical geological data in national geological cores and samples library,the result show that the factors such as metallogenic scale of gold deposits,ore deposits types,metallogenic region( belt) and metallogenic epoch etc should be considered in the process of screening of gold national-class physical geological data,besides that,the typical gold deposits with huge metallogenic potential can be taken as the screening objects. The above research results have important reference for the exploration prospecting,exploitation and utilization of the gold resources in our country.
