大东沟钼矿床位于燕辽钼成矿带，为一新发现的斑岩型钼矿床，该矿床的形成与石英斑岩关系密切。本次通过在大东沟钼矿床开展1∶5万水系沉积物测量、1∶1万土壤地球化学测量，以及激电中梯剖面测量、激电测深等，总结了矿床地质特征、地球化学异常特征、物探异常特征。地表矿化带主要产于石英斑岩及其外接触带附近；化探工作显示，地球化学异常以Mo、Zn、Pb异常为主，以石英斑岩为中心，呈环状分布于石英斑岩及其与二长花岗岩接触带附近；激电中梯异常表现为中高阻、高极化特征，分布于石英斑岩和二长花岗岩接触带附近，且与Mo、Zn、Pb异常套合较好，同时推测了矿化带在深部的延伸特征。研究认为，矿区内物化探异常明显，与地表发现的矿化体位置对应较好，综合地质、物探、化探异常特征，有效圈定了成矿有利部位，缩小了找矿靶区。通过工程验证，共发现19个钼矿体，深部找矿潜力较好，矿床规模可达中型及以上。综合找矿方法在大东沟钼矿床勘查过程中取得了较好的找矿效果，可为区域内同类型矿产勘查提供借鉴。  

The Dadonggou Molybdenum Deposit, located in the Yanliao molybdenum metallogenic belt, is a newly discovered porphyry-type molybdenum deposit genetically associated with quartz porphyry. This study integrates 1: 50 000 stream sediment survey, 1:10 000 soil geochemical survey, induced polarization (IP) gradient profiling, andIP sounding to systematically analyze the deposit's geological, geochemical, and geophysical anomaly characteristies. Surface mineralization zones are predominantly hosted within quartz porphyry and its outer contact zones. Geochemical anomalies, dominated by Mo, Zn, and Pb, exhibit a concentric distribution around the quartz porphyry and its contact zone with monzogranite. IP anomalies display moderate-high resistivity and high polarizability characteristics, spatially coinciding with the quartz, porphyry-monzogranite contact zone and overlapping well with Mo-Zn-Pb anomalies. These features further delineate the extension of mineralization at depth. The study indicates significant geophysical and geochemical prospecting anomalies within the mining area and a good correlation between them and the locations of discovered surface mineralization. By synthesizing geological, geophysical, and geochemical data, the study effectively identifies favorable metallogenic areas and narrows prospecting target areas. Drilling verification confirmed 19 molybdenum orebodies, showing promising deep prospecting potential and the prospect of a medium to large-scale deposit. The success of integrated prospecting methods in the Dadonggou Molybdenum Deposit provides a valuable reference for exploring similar deposits in the region.
