摘要: 南金山金矿是北山成矿带典型的浅成低温热液型矿床,该矿床沿NE向延伸至外围浅覆盖区,外围成矿潜力较大。为进一步实现外围浅覆盖区的找矿突破,选择开展机动浅钻地球化学测量试点工作。依据覆盖层性质及厚度,利用车载空气正循环+三翼合金刮刀钻进/气动潜孔锤钻进工艺对浅覆盖区开展机动浅钻化探取样126件,采样密度16.8个点/km2,进一步探讨了浅覆盖区浅钻化探方法技术,包括钻进工艺选择、采样网度、采样物质、样品采集等内容;对零星基岩区开展土壤测量,采集样品278件,采样密度48.77个点/km2;分析测试了Au、Ag、As、Sb、Hg、Cu、Pb、Zn、W、Sn、Mo、Bi、Cr、Co、Ni等15种元素。通过上述工作,圈定化探综合异常7处,后经异常查证在基岩区新圈定金矿体6条、银矿体1条,浅覆盖区新发现隐伏金矿体2条、银矿体1条,取得了较好的找矿效果。本次研究表明浅钻地球化学测量在北山干旱荒漠戈壁景观浅覆盖区找矿是有效可行的。Abstract: The Nanjinshan gold deposit is a typical epithermal deposit in Beishan metallogenic belt, which extends in a N-E direction to the peripheral shallow cover zone. In order to further achieve the breakthrough of prospecting in the peripheral shallow overburden area, the pilot work of motorized shallow drilling geochemical survey carried out. Based on the nature and thickness of the overburden, 126 motorized shallow drilling geochemical exploration samples are taken in the shallow overburden area using the vehicle mounted air positive circulation and three wing alloy scraper drilling or pneumatic DTH hammer drilling technology, with a sampling density of 16.8 points per square kilometer. The shallow drilling geochemical exploration methods and technologies in the shallow overburden area are further discussed, including the selection of drilling technology, sampling network, sampling materials, sample collection, etc. Soil survey was carried out in sporadic bedrock areas, and 278 samples were collected, and the sampling density was 48.77 points per square kilometer. Fifteen elements including Au, Ag, as, Sb, Hg, Cu, Pb, Zn, W, Sn, Mo, Bi, Cr, Co and Ni were analyzed. Through the above work, seven comprehensive geochemical anomalies were delineated. After anomaly investigation, six gold deposit bodies and one silver deposit body were found in the new circle in the bedrock area, and two concealed gold deposits and one silver deposit body were found in the shallow overburden area. The results show that shallow drilling geochemical survey is effective and feasible in the shallow overburden area of arid Gobi landscape in Beishan.
