没有流体作用几乎不可能形成任何有实际意义的矿床,流体是岩石圈质量和能量传输最为活跃的因素(刘建明等,1997),在成矿过程中扮演着十分重要的角色,它是成矿物质得以活化、迁移、富集的主要介质,同时流体的运移还能扩展有利的成矿空间(徐光平等,1999)。本文所说的深部流体是指 It is almost impossible to form any deposit without any fluid effect. Fluids are the most active factor in lithospheric mass and energy transmission (Liu et al., 1997) and play a very important role in the mineralization process. It is a metallogenic material To activate, migrate, enrich the main medium, while the fluid migration can also expand the favorable mineralization space (Xu Guangping et al., 1999). Deep fluid as used herein means
