At field, Fe-P and Fe-sulphide veins which injected into the anorthosites show that hydrothermal mineralization is ubiquitous. So, it is indicated that the mineralization was not only associated with the magmatic process but also with hydrothermal process. A series of petrographic, microthermometric and laser Raman spectroscopic studies on fluid inclusions in the apatite of the Fe-Ti-P ores and the quartz of the hydrothermal mineralizing stage from Heishan deposit have been carried out in this paper．Five types of fluid inclusions have been identified in the apatite and quartz. All of characteristics indicate that the ore-forming fluid belongs mainly to magmatic hydrothermal fluid．The meteoric fluid maybe plays an important role during the ore-forming process by diluting the magmatic hydrothermal fluid．
