摘　　要：坡仔营地区钼矿床是根据1:5万水系沉积物测量在坡仔营地区圈出的W、Mo元素综合异常,展开1:5万高磁测量,成果显示:在坡仔营地区Mo元素存在一个近椭圆形异常,面积约2.5km2,浓集中心明显,具浓度分带,与其重叠的有W元素异常。在浓集中心的岩体中找到了斑岩型钼矿床。在外围岩体也发现较好的的矿体化。通过物探异常、化探异常以及地质特征推测存在隐伏矿体,具有进一步寻找矿床潜力。W and Mo elements synthetic anomalies were delineated in Bozaiying area based on 1：50,000 scaled survey of stream sediments in the molybdenum ore in Bozaiying area. The achievements of 1 ： 50,000 scaled of high magnetic measurement showed that a near oval anomaly was existed in element Mo with an area of 2.5 km2, clear enriched center and concentration zoning. Porphyry molybdenum deposit was found in the rock mass of the enriched center and molybdenum minerahzation in the surrounding rock. It was concluded that there existed mineral prospecting potential in the hidden ore bodies through speculation of geophysical anomaly, geochemical anomaly and geological properties.
