英文摘要	By using Raman spectroscopy, hydrogen was detected, together with CH4, N-2, H2O, disordered graphite, and possibly a (CH4)(n)(H-2)(m) compound, in silicate melt inclusions (SMIs) in quartz from Jiajika granite in China. The occurrences of H-2 in fluid or melt inclusions are rarely reported because they are not commonly expected, and also the spectral window above 4000cm(-1) wavenumbers, where the dominant signals of H-2 located, is rarely covered in routine Raman analyses due to limited information of geological interest available in that spectral range. The mechanisms for the occurrence of H-2 in these SMIs are unknown. However, the retention of H-2 in these SMIs was most likely resulted from the low diffusion rate of H-2 in quartz at low temperatures and also the low H-2 gradient between SMIs and their environments surrounding the host minerals. More studies are needed to determine whether the occurrences of H-2 in inclusions in minerals are common in similar or other rock types, to formulate the mechanisms for its entrapment, and to investigate the associated geological processes.
