云南澜沧老厂矿区由成因、形成时代、矿化类型和产出特征等均不同的6类矿体群组成,形成"六类一体"矿化系统.其中,包括3类与早石炭世火山喷流沉积作用有关的层状矿体群和3类与喜山期隐伏花岗斑岩有关的脉状和细脉状-浸染状矿体群,前者形成于大陆裂谷环境,后者形成于陆内碰撞造山环境.它们在空间上构成特有的"三层叠三带"的矿化结构.基于矿区"双系统同位叠加"成矿模式和良好的找矿潜力,确定了6个找矿靶区,并提出了深浅并举、综合找矿、分期交叉突破的找矿思路.

There are six types of ore clusters in Laochang polymetallic deposits of Lancang, Yunnan, which are composed of poly-genesis, poly-epoch, poly-type and poly-occurrence ore bodies, and characterized by "six type in one" in mineralizing system. Three of them are stratabound ore clusters related to the Early Carboniferous volcano-exhalative sedimentary activity, which are formed in continental rift setting. The other three are vein and veinet -disseminated ore bodies related to Himalayan concealed granite-porphyry, which are formed in intracontinental collision orogenenesis setting. These six types of ore clusters constitute a special "three layers+ three zones" mineralization texture in spatial distribution. Accordingly, this paper discusses six main prospecting targets and new exploration ideas based on the bio-system syntopo-genic-superposition metallogenic model and great exploration potential.
