| 中文摘要:兰坪金顶铅锌矿床的成矿过程与油气的生成有许多相似之处，泥底辟 构造在金顶铅锌矿床的成矿过程中起着极为重要的作用。首先，随着泥底辟的上侵，塑性泥 流夹带大量气体到构造圈闭中释放压力，扩大成矿空间；其次，流体的去气作用在构造圈闭 中进行一系列的强改造活动，进而促使铅锌矿体的形成。文章通过对金顶铅锌矿床形成有关 的泥底辟流体的来源、流体形成原因、流体在张性_挤压走滑盆地阶段的演化及金顶铅锌矿 床成矿的泥底辟流体特征的分析，认为兰坪金顶铅锌矿床的形成与泥底辟构造密切相关，该 矿床具泥底辟流体的成矿特征。 |

| Abstract:The Jinding lead-zinc deposit in Lanping is genetically quite similar to the oil-gas reservoir，i.e., the mud diapiric structure played an important role in the metallogenic process of the Jinding lead-zinc deposit．First of all，with the upward invasion of mud diapir, a large quantity of gas in the plastic mud flow released pressure when it entered structural traps, thus expanding the space of mineralization．Second, fluids with the degassing effect caused a series of transformation events in the structural traps, thus contributing to the formation of lead-zinc ore bodies. The authors analyzed the source of the mud diapiric fluid, the formation of the fluids, and the mud diapiric fluid metallogenic characteristics of the Jinding lead-zinc deposit. On such a basis, it is believed that the Jinding lead-zinc deposit is closely related to the mud diapiric structure and that this ore deposit has mud dispiric fluid metallogenic characteristics. |
