| Abstract: | It was adopted that the fluorescence microscope, Gas-Flow Heating/Freezing System, Laser-Raman Spectroscopy, etc. are the multimedia techniques for analysing fluid inclusions of quartz veins in Budate Group, Hailar Basin.The results show that fluid inclusions in quartz veins are small (1 ～5 μm) monophase, two-phase (liquid+vapour)aqueous inclusions; the two-phase aqueous inclusions homogeniese to the liquid phase between 120 ～ 180℃, two Laser-Raman Spectroscopy show that both gas phase are enriched in CH4 (94.50% ～99.25% ) and C6H6 (0.75% ～2.70%), under these conditions, inclusions may have come from juvenile fliud followingly the quartz veins formation.While the quartz veins exhibiting different striking luminescence has been proved by cathodoluminescence, it would be belong to secondary hydrocarbon inclusions. The oil inclusions of this stage represent mainly the large scale of oil accumulation, located within the quartz microfracture. |
