赣南宁都地区1∶50 000青塘幅矿产地质图数据集

青塘幅位于江西南部于都银坑−宁都青塘整装勘查区北部，于山成矿亚带的北部。本次工作采用了岩性−构造−蚀变矿化专项填图、遥感、物探、化探、钻探等多种方法进行数据采集，完成了矿产地质路线调查长度533.68 km，采集水系沉积物样品1 729件，完成1∶50 000地面高精度磁法测量458 km2，遥感数据解译面积458 km2，钻探施工422 m，化学分析样119件。数据集重点对燕山期早阶段成矿岩浆岩、含矿建造、控岩控矿构造及矿化蚀变标志等进行了调查划分，明确黑云母花岗岩为矽卡岩型硫铁钨多金属矿的成矿地质体，主要成矿结构面为梓山组上段的硅钙异性界面，蚀变以矽卡岩化、大理石化等为主；编制了青塘幅建造构造图，创建了区内矿产数据库，汇编了主要建造构造、断裂、地质界线、岩浆岩等属性特征；完善了狮吼山式矽卡岩型硫铁钨多金属矿床找矿预测模型，突出了区内矿产与建造构造之间的成因联系。

The Qingtang Sheet is situated in the northern part of the Yudu Yinkeng-Ningdu Qingtang Integrated Exploration Area in southern Jiangxi, as well as the northern segment of the Yushan Metallogenic Subzone. This study collected data using multiple methods including lithological-structural-alteration-mineralization specialized mapping, remote sensing, geophysical prospecting, geochemical exploration, and drilling. A total of 533.68 km of mineral geological route surveys were completed, 1,729 stream sediment samples were gathered, 458 km² of 1:50,000 ground high-precision magnetic surveys were conducted, remote sensing data interpretation covered an area of 458 km², 422 meters of drilling work was finished, and 119 chemical analysis samples were prepared. The dataset focuses on investigating and classifying Early Yanshanian ore-forming magmatic rocks, ore-bearing formations, ore-controlling structures, and mineralization alteration markers. It confirms that biotite granite serves as the ore-forming geological body for skarn-type iron-sulfide-tungsten polymetallic deposits, the primary ore-forming structural plane is the silica-calcium heterovalent interface of the upper member of the Zishan Formation, and the main alteration types are skarnization and marbleization. We compiled the formation and structure map of the Qingtang Sheet, established a local mineral resource database, and compiled attribute features of major formation structures, faults, geological boundaries, and magmatic rocks. Additionally, the prospecting prediction model for the Shihoushan-type skarn-type iron-sulfide-tungsten polymetallic deposits was improved, highlighting the genetic connection between mineral deposits and formation structures within the study area.
