| [摘 要] 大平掌铜多金属矿属火山喷流沉积矿床，发育V1和V2两类矿体，其中，V1矿体为块状硫化物矿体，V2矿体为细脉浸染状矿体，二者构成VHMS型矿床所具有的“上层-下脉”及“上黑-下黄”的空间矿化结构。本文通过研究区域地质背景、成矿地质特征、结合矿区演化特点，建立大平掌铜矿成矿模式，对分析原特提斯期的铜多金属成矿作用及其类型，提升“三江”成矿带典型矿床研究水平，认识思茅盆地早古生代基底中的优势成矿类型、找矿潜力和找矿思路等，有重要的启示作用。 |

| Abstract: The Dapingzhang copper poly-metallic deposit is a volcanic exhalation - sedimentary deposit, which hosts two types of ore bodies. Of them, one is massive sulfide ore (V1), and the other is veinlet-disseminated ore (V2). The deposit exhibits a similar mineralization space structure with the VHMS type deposit, i.e., the upper part of the ore body is characterized by “layering and black” and the down part is “veinlet and yellow”. Based on the analysis on regional geological background, metallogenic characteristics and combined with evolution characteristics of the ore district, we established a metallogenic model for the Dapingzhang copper polymetallic deposit. It has significant implications for analyzing the proto Tethys of copper poly-metallic mineralization and its type, promoting the research of the "Sanjiang" metallogenic belt, and thus shedding light on the dominant metallogenic types of the Simao basin’s early Paleozoic basement and prospecting potential and prospecting ideas. |
