郭家岭岩体矿物包裹体研究

STUDY ON MINERAL INCLUSIONS IN GUOJIALING INTRUSIVE

摘要:

通过对胶东金成矿区郭家岭岩体中熔融包裹体、含石盐子晶包裹体、ＣＯ２三相包裹体和Ｈ２Ｏ两相包裹体的显微测温，结果表明，该岩体在岩浆结晶晚期发生过高盐度流体与硅酸盐熔体的不混熔过程。根据熔融包裹体均一温度与均一过程的时间，利用相应公式，计算出郭家岭岩体包裹体熔体的粘度和含水量，认为该岩体是从一种高温高粘度的岩浆中结晶成岩的。

Abstract:

By the microthermometry of melting inclusion,daughter crystal of halitebearing inclusion,three-phase of CO2 inclusion and twophase of H2O inclusion in Guojialing intrusive in Jiaodong gold mineralization field. It demonstrates that the intrusive experienced an incompatible period between high salinity fluid and silicate melt in late crystallization time of the intrusive. According to homogenization temperature and its time of the melting inclusion,viscosity and water content of the inclusion melt in Guoji...
