中文摘要:
      东磨子沟爆破角砾岩体平面上呈环状分布,围绕爆破角砾岩体与地层接触带,发育构造破碎带,土壤地球化学测量成果显示异常沿爆破角砾岩体边部呈环状分布。深部施工的钻孔,控制爆破角砾岩体呈桶状,围绕桶状体的边部圈定了金、铜、钨矿体。通过钻孔岩石化探分析,东磨子沟金多金属矿体的构造叠加晕特征明显,通过工程验证,7个钻孔中有5个钻孔见矿,2个具有明显的化探异常,数据分析与实际生产一致,显示东磨子沟金矿深部具有良好的找矿前景,为下一步工作指明了方向。
英文摘要:
      The Dongmozigou blasting breccia displays a ring distribution on plane. It develops a tectonic fracture zone around the contact zone between the blasting breccia and stratum. The results of soil geochemical survey show that the abnormal breccia is distributed in a ring along the edge of the blasting breccia. In deep drilling, the controlled blasting breccia body is shaped like a barrel, and the gold, copper and tungsten ore bodies are delineated around the edge of the barrel body. Drilling rock geochemical analysis indicates that the Dongmozigou gold polymetallic ore body has clear structural superimposed halos. Engineering validation suggests that, among the seven drill holes, five drill holes intersect ores, and two drill holes show significant geochemical anomalies. The data analysis is consistent with the actual production, indicative of a good prospecting potential of this deposit, which has pointed out prospecting direction for the future work.
