摘要
粗榆金矿床位于吉林省,属于岩浆热液脉型金矿床,其矿体主要受NE向断裂控制。采用粗榆金矿床原生晕的分带性在矿床深部和外围展开地质勘查工作,取得了显著成果。通过地质和地球化学分析,建立了盲8号矿体的构造叠加晕模型。分析结果显示,金(Au)与其他亲硫元素有显著相关性,表明这些元素在矿化过程中有共同的成矿行为。通过聚类分析、相关分析和因子分析,成功识别出与成矿相关的元素组合,建立元素地球化学分带序列。依据构造叠加晕的标志,预测盲5至盲10号矿体的深部矿体存在,并通过钻探工程验证,预测靶区确实存在金矿体。这项研究表明,构造叠加晕方法在矿山深部找矿中的有效性,为未来的矿产资源勘探提供了重要的技术支持。
The Cuyu gold deposit is located in Jilin Province,and belongs to the type of volcanic hydrothermal vein gold deposit,whose ore bodies are mainly controlled by NE-trending faults.Significant achievements have been made in geological exploration of the deep and peripheral areas of the deposit by using the zoning of the primary halo of the Cuyu gold deposit.Through geological and geochemical analysis a structural superposition halo model of the blind No.8 ore body was established.The analysis results show a significant correlation between gold(Au)and other sulfur-loving elements,indicating that these elements have a common mineralization behavior during the ore-forming process.Through cluster analysis,correlation analysis,and factor analysis,the element combinations related to mineralization were successfully identified,and an element geochemical zoning sequence was established.Based on the signs of the structural superposition halo,it is predicted that there are deep ore bodies in the blind No.5 to No.10,and through drilling engineering verification,it is confirmed that there are indeed gold ore bodies in the predicted target area.This study demonstrates the effectiveness of the method of structural superposed halo in deep mineral exploration,providing important technical support for future mineral resource exploration.
