    摘要:

    吉林省石人镇幅(K52E013003)1∶50 000矿产地质图是依据《矿产地质调查技术要求(1∶50 000)》(DD2019-02),在充分利用原1∶50 000区域地质调查工作成果资料的基础上,以成矿作用类型为主线、以成矿要素为对象、以预研究为基础、以矿产地质专项填图为核心,采用室内与室外填编图相结合的方法完成的。该工作积极探索创新了矿产地质专项填图成果表达方式,基本查明石人镇幅地层层序并详细划分了沉积岩、侵入岩和变质岩的建造类型,在建造构造图的基础上添加地理信息及矿产信息编制矿产地质图,突出成矿信息的表达。在矿产综合检查、成矿规律总结的基础上,初步圈定金找矿靶区6处,预测资源量65.09 t,为今后找矿突破提供了基础地质依据及找矿方向。本数据库包含1张MapGIS矢量矿产地质图,以及7个样品的全岩地球化学分析数据,20个样品的主量、微量和稀土元素的岩石地球化学分析数据和16个样品的锆石U-Pb同位素测年数据,13条金及多金属矿产地信息,矿床成因类型分别为石英脉型和蚀变岩型,累计查明资源储量矿石量 1098.41 ×104 t,金的金属量49 989 kg,矿床平均品位4.55 g/t,数据容量约80.70 MB。该数据库充分反映了1∶50 000矿产地质专项填图成果,为今后找矿提供了基础地质依据及找矿方向。

    Abstract:

    The 1∶50 000 mineral geological map of the Shiren Town map-sheet (K52E013003) in Jilin Province was prepared by adopting indoor and field mapping (compilation) according to the Technical Requirement of 1∶50 000 Solid Mineral Geological Survey (DD 2019-02), during which the results of previous 1∶50 000 regional geological surveys were fully utilized. With mineralization types as the main line, this project focused on mineral and geology-specific mapping based on a preliminary study and mainly researched metallogenic factors. Meanwhile, the presentation of geology-specific mapping results was actively explored and innovated, the stratigraphic sequences of the Shiren Town map-sheet were basically ascertained, and the sedimentary rock suites, intrusion suites, and metamorphic rock suites were determined in detail. The map was completed by adding geographic data and mineral resource information to the suite-tectonic map, highlighting the expression of metallogenic information. The database of the map (also referred to as the Database) contains a mineral geological vector map in MapGIS format, whole-rock petrogeochemical data of seven samples, petrogeochemical data of major, trace, and rare earth elements of 20 samples, and zircon U–Pb isotopic dating data of 16 samples. Besides, it includes the data of 13 gold and polymetallic deposits, whose genetic types are quartz vein and alteration types. The total amount of resource reserves is 1098.41×104 t, and that of gold is 49 989 kg, with the average Au grade of 4.55 g/t. With a data size of about 80.70 MB, the database fully reflects the results of 1∶50 000 mineral and geology-specific mapping, thus providing basic geological bases and prospecting direction for future strategic actions on prospecting breakthroughs.
