西藏羊八井-林周地区水热成矿系统与模拟

在区域成矿构造系统的控制之下，羊八井-林周地区新生代水热成矿随着高原的隆起过程，显示了由羊八井向东、时间由新到老、成矿热液氢氧同位素呈现有规律变化，形成一个由断裂网络和热源驱动控制的水热成矿系统。概括三维有限元构造应力场和热模拟对区域构造力、热力驱动的模型进行设计、计算分析，及天然地震统计分析结果，作者认为在研究区存在一个一直延续至今的水热成矿典型区域和通道，具有重要的构造动力成岩成矿的理论意义，并且在寻找构造、热驱动的水热矿床方面得到实际应用。

HYDROTHERMAL ORE-FORMING SYSTEM IN THE YANGBAJAIN-LHÜNZHUB AREA, TIBET, AND ITS NUMERICAL SIMULATION

With the control of the regional metallotectonic system, To the east from Yangbajing and Time from new arrive old, the isotopic analyses of hydrogen and oxygen from hydrothermal presents the regulation variety along with the plateau uplift. The Hydrothermal Metallogenesis System with the control of the fault network and heater drive. According to the computation and analysis of the tectonic stress, heat simulation and the deepth of earthquake focus, it can be formed that there is a type area of Hydrothermal Metallogenesis System until now. It has very important theories meaning of the dynamic metallotectonic and has got the actual application in the finding structure and hydrothermal mineral deposit driven by heat.
