THE CHARACTERISTICS OF ORE-CONTROLLING STRUCTURE IN THE BAOSHAN CU-PB-ZN POLYMETALLIC DEPOSIT, HUNAN PROVINCE

Development and Research Center, China Geological Survey, Beijing 100037, China

摘要

摘要: 宝山铜铅锌多金属矿床位于南岭成矿带中段北缘，分为中区的矽卡岩型铜钼矿、外围的热液型铅锌银矿床，具有明显的水平矿化分带性，矿体受构造控制。通过野外工作及室内综合研究认为，宝山铜铅锌多金属矿床的形成具有多期性。矽卡岩形成时期的控矿构造为F₀断层，金属硫化物形成时期的控矿构造为F₂₁与F₂₅断层。F₀、F₂₁、F₂₅断层为含矿热液运移的主要通道，倒转背斜、向斜构造则为含矿热液的富集成矿提供了良好的空间。

Abstract: The Baoshan Cu-Pb-Zn polymetallic deposit is located in the northern margin of the middle section in the Nanling metallogenic belt. It is divided into the middle skarn type copper-molybdenum ore and the peripheral hydrothermal type lead-zinc-silver deposit. It has typical zoning characteristics. The ore body orientation is controlled by structure. According to the occurrence of ore bodies, it can be seen that the formation of Baoshan copper-lead-zinc polymetallic deposits is multi-stage. The ore-controlling structure of the skarn formation period is the F₀ fault, and the ore-controlling structure during the metal sulfide formation period is the F₂₁ and F₂₅ faults. The F₀, F₂₁ and F₂₅ faults are the main channels for ore-bearing hydrothermal migration, and the inverted anticline and syncline structure provide a good space for the rich ore containing ore-bearing hydrothermal fluid.
