| 摘 要： | 本数据集综合应用岩性-构造-矿化蚀变专项填图、遥感、物探、化探、钻探等多种方法进行数据采集，完成路线调查长度520.65 km，采集水系沉积物样品2 047件，遥感数据解译面积461 km2，化学分析样167件。重点对燕山早期成矿岩浆岩、含矿建造、控岩控矿构造，以及矿化蚀变标志等进行了调查划分，明确区内银金多金属矿主要成矿地质体为燕山早期花岗闪长岩，控岩控矿构造为北东向逆冲断裂及其次级裂隙。在此基础上，编制了1：50 000银坑幅建造构造图，利用数字化填图系统（DGSS）创建了区内矿产地质图数据库，全面汇编了重要建造构造、地质界线、断裂、岩浆岩等图层属性库；完善了银坑式中低温岩浆期后热液矿床找矿预测模型，突出了区内矿产与建造构造之间的成因联系。

| Abstract: | In order to develop this dataset, data were acquired comprehensively by using multiple methods such as mapping which is specific for lithology, structures and mineralized alterations, remote-sensing, geophysical/geochemical and drilling exploration. A route of 520.65 km was surveyed, with 2 047 stream sediment samples and 167 chemical analytical samples collected, and 461 km2 area interpreted based on remote-sensing data. Emphasis was placed on survey and division of early-Yanshanian metallogenic magmatite, ore-bearing formations, rock-control and ore-control structures, and mineralized alteration marks etc., so that it could be verified that the main metallogenic geological bodies for Au-Ag multi-metal ores within the area were early-Yanshanian granodiorite and that the rock-control and ore-control formations were a NE-strike thrust fault and its secondary fissures. Building on this, the 1:
50 000 formation and tectonic map of the Yinkeng Map-sheet was compiled, the mineral geological map dataset was established by using a digital mapping system (DGSS), a map layer property database on key formations & tectonics, geological boundaries, fractures and magmatite etc. was comprehensively compiled; the prospecting prediction model for Yinkeng-style mid-low temperature post-magmatic hydrothermal deposits in the area was improved, highlighting the causal relationship between deposits and the formations or structures in the area. |
