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 Lancang Old Factory Polymetallic Deposit in Yunnan Province is an important polymetallic deposit in the “Sanjiang” metallogenic belt. It is located in the Lancang rift to the south of the Changning-Menglian rift zone to the west of the Lancangjiang fault. The evolution of tectonic environment in this area has undergone three major changes in the continental rift period, closure and collision orogeny. The three favorable ore-forming tectonic settings are replaced by the superposition and coupling features of various important metallogenic geology. The deep large molybdenum (copper) ore body of No. VI exposed in the deep of the mining area belongs to the skarn and porphyry deposits related to the Xishiyama porphyry and is one of the ore-forming types and resource types that made a major breakthrough in prospecting in the mining area. This paper combines the Lancang old mining area of the earth, objects, chemical and remote information on the molybdenum resources research, forecast, predict the scale of molybdenum resources - large. Based on the analysis of the characteristics and resource prospect of the molybdenum plant in Lancang old factory, it is hoped that the attention will be paid to the old plant and the periphery of Lancang prospecting, which will provide a far-reaching impact on the prospecting breakthrough in this area.
