摘要:

二道坎银铅锌矿床是近年来在多宝山矿集区新发现的一个大型独立银矿床,其是黑龙江省发现的首个独立银矿床,也为探讨区域成矿规律提供了重要的研究案例。针对二道坎银铅锌矿床缺乏系统研究且深部勘查程度较低的现状,通过系统收集并整理矿区地质、钻探、地球化学等多源数据资料,利用Micromine软件建立了矿区三维地质模型,在“三位一体”找矿预测理论的指导下,结合立方体预测与找矿信息量法开展了深部成矿预测,最终圈定了 4处找矿靶区。研究结果表明,二道坎银铅锌矿区构造角砾岩,北东向和北西向断裂交会部位,Ag、Pb、Zn异常等可作为直接找矿标志,在矿床深部仍具有较大找矿潜力。

Abstract:

The Erdaokan Ag-Pb-Zn Deposit is a large independent silver deposit recently discovered in theDuobaoshan ore province. It not only represents the first independent silver deposit found in Heilongjiang Province butalso provides a significant case study for understanding regional metallogenic regularity. Owing to the lack of systematicresearch and low degree of deep exploration in the Erdaokan Ag-Pb-Zn Deposit, multi⁃source data, including geological,drilling, and geochemical information, were systematically collected and integrated. By using Micromine software, a 3Dgeological model of the mining area was established. Guided by the "trinity" prospecting prediction theory, deep mineralprediction was conducted by integrating the cube prediction method and the information quantity method for prospecting,resulting in the delineation of 4 prospecting target areas. Results indicate that structural breccias, intersections of NE⁃and NW⁃trending faults, and Ag,Pb,Zn anomalies in the Erdaokan Ag-Pb-Zn District can serve as direct prospectingindicators, suggesting substantial exploration potential remains at depth.
