摘要
兰坪矿集区是西南三江成矿带的重要组成部分,已发现有大型-超大型铅锌多金属矿床,找矿潜力巨大。文章在分析兰坪矿集区典型矿床特征的基础上,依据构造旋回、含矿建造、成矿时代、成矿作用,将兰坪矿集区中的矿床划分为2个成矿系列、5个成矿亚系列,并对成矿系列的时空分布特征、成矿规律进行了论述,其中燕山期与晚三叠世海相沉积作用有关的铅锌矿床和喜玛拉雅期与沉积、填充交代作用有关的铅锌银铜钴多金属矿床是兰坪矿集区的主要成矿类型。
Lanping ore-deposit-clustered area is an important part of three （Lancangjiang, Nujiang and Jinshajiang） river metallogenic belt in Southwest China. In the area large-super-large Pb-Zn deposits have been discovered. However it is still potential for further prospecting. On the basis of tectonic cycles, ore- bearing formations, ore-forming ages and mineralization in ore deposits the area are divided into two min- erogenetic series and five sub-series. Temporal-spatial distribution pattern and metallogenic regularity of the deposits are discussed. The Late Triassic （Yanshanian） marine sedimentary Pb-Zn deposits and the Himalayan sedimentary, filling-replacement Pb-Zn-Ag-Cu-Co polymetallic deposits are the two main types of ore deposit in the area.
