    摘要:

    胶东成矿区栖霞—牟平地区地质矿产调查是中国地质调查局开展新一轮矿产地质调查工作项目。填(编)的10幅1∶50 000矿产地质图是根据《固体矿产地质调查技术要求(1∶50 000)》(DD 2019−02)和行业其他统一标准及要求,结合区域地质调查成果资料,采用数字填图系统进行野外地质专项填图,并应用室内与室外填编图相结合的方法完成的。在充分利用最新获得的1∶50 000遥感地质解译、地面高精度磁法测量、重力测量成果资料的基础上,全区新发现矿点矿(化)点31处,包括金矿(化)点24处、铜矿点4处、银铅矿点3处,圈定找矿靶区42处,其中A级25处、B级14处、C级3处,并纳入数据库中。胶东成矿区栖霞—牟平地区地质矿产调查数据库是1∶50 000矿产地质图库和图饰、地球物理数据库、遥感数据库、样品数据库、综合成果数据库、勘探工程库等成果的集成,数据容量合计299 MB,包含矿产地数据275处,涉及多金属矿、贵金属矿以及非金属矿23种,预测金资源量836.94 t、银499 t、铜72.71万t、铅17.41万t、锌28.31万t、钼35.70万t、钨2.8万t、石墨164万t。对该区基础地质研究、矿产资源勘探等具重要参考意义。

    Abstract:

    The geological and mineral survey in Qixia–Muping area, Jiaodong metallogenic province (also referred to as the survey site) is one of a new round of mineral and geological survey projects initiated by the China Geological Survey. During this project, ten 1∶50 000 mineral geologic maps were mapped (prepared) in accordance with uniform industrial standards and requirements such as the Technical Requirement of 1∶50 000 Solid Mineral Geological Survey (DD 2019–02). Meanwhile, the results of relevant regional geological surveys were adopted, special geological field mapping was conducted by using digital mapping, and indoor mapping (preparation) was combined with outdoor mapping (preparation). Thirty-one ore occurrences (mineralized points) were newly discovered, and 42 prospecting target areas were delineated throughout the area by making full use of the latest results of geological interpretation of 1∶50 000-scale remote sensing data, high-precision ground magnetic survey and gravity survey. Among them, the former consists of 24 gold ore occurrences (mineralized points), four copper ore occurrences and three silver–lead ore occurrences, and the latter is composed of 25 areas of grade A, 14 areas of grade B, and three areas of grade C. All these survey results were included in the database. The geological and mineral survey database of Qixia–Muping Area, Jiaodong Metallogenic Province (also referred to as the Database) integrates the databases of 1∶50 000-scale mineral and geological maps and their map decorations, geophysical databases, remote sensing databases, sample databases, comprehensive result databases, and prospecting engineering databases, with a total data size of 299 MB. It covers the data of 275 mineral occurring sites, and 23 species of polymetallic, precious metallic and non-metallic deposits. The resources of Au, Ag, Cu, Pb, Zn, Mo, W and graphite are predicted to be 836.94 tonnes, 499 tonnes, 727 100 tonnes, 174 100 tonnes, 283 100 tonnes, 357 000 tonnes, 28 000 tonnes and 1.64 million tonnes, respectively. The Database serves as an important reference for basic geological research and exploration of mineral resources in the Qixia–Muping area.
