云南省澜沧老厂钼矿特征及资源前景

Characteristics and Resource Potential for Molybdenum Minerals of Laochang in Lancang, Yunnan Province

云南澜沧老厂多金属矿区是"三江"成矿带中重要的多金属矿床。位于滇西澜沧江断裂以西的昌宁—孟连裂谷带南段的澜沧裂谷中。该区构造环境演化历经了大陆裂谷期、封闭、碰撞造山期3次重大体制的转变。三大有利成矿构造环境更替,多种重要成矿地质作用的叠加和耦合特征明显。矿区深部揭露的Ⅵ号厚大钼(铜)矿体群属喜山期斑岩有关的夕卡岩、斑岩型矿床,是矿区取得找矿重大突破的成矿类型和资源类型之一。本文结合了澜沧老厂矿区的地、物、化、遥等信息对钼资源进行研究、预测,预测钼资源规模达大-超大型。通过对澜沧老厂钼矿特征及资源前景研究分析,以期引起澜沧老厂及外围深部找矿的重视,为该区找矿突破提供深远影响。

The copper-molybdenum deposit of Laochang in Lancang, Yunnan Province, China, is skarn and porphyry ore deposit related to the Yanshanian porphyry. Its metallogenetic geological setting and geological characteristics of deposits obviously display comprehensive correspondence in the respects of geophysics, geochemistry and remote sensing interpretation. In view of above, the prognosis of synthetic information was employed to obtain prediction and evaluation on prospect for molybdenum ore resources of Laochang in Lancang, in this study.
