摘要
20号地区位于明月峰岩体的北东外接触带,已落实两个铀矿床.铀矿化主要赋存在中泥盆统富含黄铁矿和有机质的泥岩碎裂岩和角岩中。通过1:10000放射性水化普查,在84Km^2范围内圈定出18个水化异常片,总面积7.2km^2,占普查面积的8.3%。矿床勘探结果表明,地下水化异常迁移距离为200—500m,反映矿化深度为100—200m。
The area No.20 is situated in the northeastern part of the exocontact zone of a granite massif, where two uranium deposits have been confirmed. Uranium mineralization mainly occurs in Middle Devonian cataclastic pelite and hornstone rich in pyrite and organic. matters. Through radioactive hydrochemical prospecting at 1:10000 scale, 18 areas of radioac- tive water anomalies were outlined and the total anomaly area is 7.2km^2, accounting for 8.3% of the total area of 84km^2. The results of exploration show that the migration of groundwater anomalies is at a distance of 200--500m, indicating the uranium mineralization at the depth of 100--200m.
