【摘要】 达热尔金矿床位于东昆仑造山带沟里矿集区，是新发现的一处小型金矿床。随着浅地表勘查工作的结束，为扩大矿床规模，寻找深部矿产资源的需求日趋迫切，而矿床原生晕是寻找深部盲矿体最直观且高效的方法之一。采用岩石地球化学方法对达热尔金矿床63号勘探线采集的209件样品进行分析测试，分析了Au、Ag、Cu、Pb、Zn、W、Sn、Mo、As、Sb、Hg、F、Mn、Bi和Co共15种元素含量。采用R型聚类分析方法对元素组合特征进行深入研究，确定AⅡ矿体的近矿晕元素为Au、Cu、Pb、Zn和Ag，前缘晕元素为F、Sb、As和（Hg），尾晕元素为Mo、Co、Bi、Mn、Sn和（W）；运用格里戈良原生晕分带指数法对金矿体原生晕特征进行分析，得出自上而下金矿体的原生晕轴向分带序列为Zn-W-Hg-Ag-Sn-Cu-Mo-Co-Au-S-Mn-F-Pb-AsBi，具有明显的“头尾晕共存”和“反分带”特征，并表现出弱Au异常晕。结合可控源音频大地电磁测深反演的深部异常特征，认为该区找矿潜力巨大，推测深部存在盲矿体或矿体向深部有延伸趋势。结合地物化特征，对63号勘探线南北两侧的55号和71号勘探线开展了深部钻孔验证，均揭露出金矿体，金品位最高达27×10-9，取得了良好的找矿效果，并验证了原生晕找矿方法的有效性。更多还原

【Abstract】 The Dareer gold deposit, situated within the Gouli mineralized district of the East Kunlun orogenic belt, represents a recently identified small-scale gold deposit. To facilitate deeper exploration and enhance the deposit’s scale, it is imperative to conduct further investigations beyond the preliminary surface studies. The primary halo method is recognized as one of the most direct and effective approaches for this purpose.Consequently, geochemical analyses were performed on 209 samples collected from No.63 exploration line in the area, examining 15 elements including Au,Ag,Cu,Pb,Zn,W,Sn,Mo,As,Sb,Hg,F,Mn,Bi,and Co.Utilizing the R-type cluster analysis method, the study identified the elemental associations characteristic of the deposit. The near-ore halo elements for the AⅡ orebody were determined to be Au,Cu,Pb,Zn,and Ag.The front halo elements were identified as F,Sb,As, and Hg.The tail halo elements were found to be Mo,Co,Bi,Mn,Sn,and W. Utilizing Grigorian calculation methods for axial zoning, the primary halo of the orebody from top to bottom was identified as follows: Zn-W-Hg-Ag-Sn-Cu-Mo-Co-Au-S-Mn-F-Pb-As-Bi. This sequence exhibits distinct characteristics of “coexistence of head and tail halo” and “reverse zoning”with a weak anomalous Au halo present. Based on the deep anomaly features revealed by controlled-source audio-frequency magnetotellurics(CSAMT) inversion in the area,there is significant potential for mineral exploration,suggesting the possible presence of blind ore bodies or ore bodies extending deeper into the earth. In light of the geophysical and geochemical characteristics, deep drilling verification was conducted on the No.55 and No.71exploration lines, flanking the No. 63 exploration line. This led to the discovery of orebodies with the highest grade reaching 27×10-9,thereby achieving excellent prospecting results and confirming the efficacy of the research methods employed.更多还原
