Method for identifying inclusion of ore-forming fluid in sandstone type uranium deposit

The invention belongs to the technical field of uranium ore geology, and particularly relates to a method for identifying inclusion of ore-forming fluid in sandstone type uranium ore, which comprises the following steps of: 1, collecting a uranium ore sample in the field; step 2, manufacturing a fluid inclusion sheet with two polished surfaces; step 3, performing diagenesis stage division on the fluid inclusion sheets; step 4, performing fluid inclusion type and period division on the fluid inclusion sheet; 5, standard minerals/substances in the uranium mineralization period are established; and 6, identifying the fluid inclusion in the mineralization period. According to the method, sandstone uranium ore samples are screened, processed and manufactured, comprehensive analysis is carried out under a polarization-fluorescence microscope, a scanning electron microscope, an electron probe, a laser Raman spectrometer and other instruments, and therefore the uranium ore-forming fluid is accurately recognized, a fo
