| 中文摘要:为查清深部隐伏矿体规模和延伸情况，在新地沟和卯独庆化探异常区，开展了激电法(中间梯度装置)和高精度磁法测量。新地沟化探异常区圈出面积约10 km2的激电异常和磁异常，异常尚未封闭，有大幅度向外延伸的趋势；卯独庆化探异常区圈出面积约2.5 km2的激电异常。激电异常与化探异常基本吻合，应为同源异常。经验证，新地沟和卯独庆激电异常均为原生矿体引起，表明综合物化探方法是寻找隐伏矿体的最廉价、最适用、最有效的方法。 |

| Abstract:To find out sizes and extensions of concealed orebodies in the depths, the authors carried out IP (intermediate gradient device) and high precision magnetic survey in Xindigou and Maoduqing geochemical anomaly areas. In Xindigou geochemical anomaly area, an IP and magnetic anomaly of some 10 km2 was delineated, which is not closed and shows remarkable trend of outward extension. In Maoduqing geochemical anomaly area, an IP anomaly of about 2.5 km2 was delineated. The IP anomaly is on the whole consistent with the geochemical anomaly, suggesting that they are cogenetic anomalies. Inspection shows that IP anomalies in Xindigou and Maoduqing are both induced by primary orebodies. It is thus concluded that the integrated geophysical_geochemical exploration method is the most cheap, most practical and most effective method in prospecting for concealed orebodies. |
