国家级铅锌矿实物地质资料筛选

铅、锌是我国重要的战略性矿产资源,也是全国实物地质资料馆采集保管的重点矿种。我国铅锌矿产资源丰富,但实物地质资料管理方面仍较为薄弱。在分析我国铅锌矿产资源赋存特点、时空分布和主要类型的基础上,参照矿产资源实物地质资料的筛选原则,提出筛选铅锌矿床实物地质资料的主要考虑因素,确定筛选名录。从21片国家级重点成矿区(带)出发,初步筛选出38个具有代表性的铅锌矿床作为国家实物地质资料馆优先收藏的对象。反映了中国铅锌矿的成矿特点和地质勘查水平,为系统开展铅锌矿实物地质资料采集提供了必要的依据。

Screening of National physical geological data on lead-zinc deposits in China

Lead-zinc metals are not only important strategic mineral resources in China, but also one of the most important mineral resources screened, collected and managed by National Physical Geological Data Centre. Lead-zinc mineral resources are very abundant all over our country, but the management of their physical geological data is relative weak. Based on the analysis of the occurrence characteristics, spatial and temporal distribution and the main types of lead-zinc resources, and referencing to screening principle of physical geological data of mineral resources, this paper puts forward the major consideration factors on screening of Lead-zinc mineral resources, and determines the screening list. Preliminary screens 38 representative lead-zinc deposits from 21 national important metallogenic belts to managed by National Physical Geological Data Centre, which is not only a reflection of metallogenic characteristics and level of geological prospecting of lead-zinc, but also a necessary basis for systematic collection of lead-zinc deposits.
