| 摘 要： | 粤东单竹坑矿区位于曾公嶂铅锌多金属矿集区,周边已发现多个多金属矿床,区域找矿前景优越。根据区域物化探异常圈定了找矿远景区,结合矿区的地质成矿特征,选择有利地段开展大比例尺物化探扫面和地质填图,逐步明确了找矿靶区,查明了矿体的走向和分布范围。在此基础上,针对性地布置了CSAMT测深,推断了矿体的深部形态、规模和产状,为钻探工程验证提供了可靠的依据。通过钻探验证,在矿化带内的物化探综合异常浓集中心,发现了多个高品位铅锌银多金属矿体,找矿成果丰硕。地-物-化综合找矿方法在单竹坑矿区的应用是行之有效的,对区域上同类型矿床的勘查工作起到了一定的借鉴作用。

| Abstract: | Danzhukeng mining area is located in the concentration area of Zenggongzhang volcanic basin. Many polymetallic deposits have been found around it, regional prospecting potential is great.The prospecting range is determined by geophysical and geochemical anomalies in small scale area.The prospecting range is determined by regional geophysical and geochemical anomalies.Combined with the geological and metallogenic characteristics of the mining area,selecting a favorable areas for large-scale geophysical and geochemical ex-ploration and geological mapping, the prospecting target area has been defined step by step, and the trend and distribution range of ore bodies have been ascertained.On this basis, the CSAMT sounding is arranged perti-nently, and the deep shape, scale and occurrence of the orebody are inferred, providing an effective basis for en-gineering verification.Drilling at the sites with geophysical and geochemical anomalies reveals several Pb-Zn-Ag polymetallic ore bodies with large thickness and high grade, good prospecting results have been achieved. The application of comprehensive geophysical and geochemical prospecting method is effective and feasible, and plays a guiding role in regional mineral exploration. |
