Abstract: The cathodoluminescence is a crystal luminescence caused by that the streams of electrons from cathode are directed onto the crystal surface.Usually, the trace elements in crystal are the activator that influnce the formation of luminescence center. The composition ofore-bearing fluid has been changing during the growthing of crystal. So the same minerals which have different generations or the growth zones of a mineral crystal have different luminescence under the cathodoluminescence microscope. It is helpful to distinguish the different generation minerals and a crystal microstrctural marakers in which the fluid inclusions can be finded. The sample which come from Guangtoushanaklali granite ,Wendeng gold deposit and Shuikoushan silicalite are studied under the cathodoluminescence microscope. In this background, detail P-T-V-X properties of fluid are determined from the further studying the fluid inclusions.

Key words: cathodoluminescence, fluid inclusions, minerlization and lithogenesis
