英文摘要Fatty acids were extracted from fluid inclusions, and analyzed for distribution and individual delta C-13 values to determine if there exists sulfate-reducing bacteria (SRB) and what substrates SRB depleted during U mineralization in the Dongsheng deposit. The 10-methylhexadecanoic acid (10Me16:0) has been detected from most of the samples using GC-MS based on relative retention time and co-injection of standard 10Me16:0 compound. Samples with higher 10Me16:0 concentrations, show higher U contents. The presence of 10Me16:0 along with iso-omega 7-cis-heptadecenoic acid (i17:1 omega 7c) and omega 7-cis-octadecenoic acid (18:1 omega 7c) in the fluid inclusions may indicate the occurrence of SRB during the U mineralization. Saturated fatty-acids and unsaturated fatty-acids detected in this study have individual delta C-13 values from -30.3aEuro degrees to -28.5aEuro degrees and -30.5aEuro degrees to -27.9aEuro degrees, respectively. These values are close to those of n-alkanes of the associated oils and the bulk oils, but significantly distinct from methane, thus the oils are concluded to have been used as substrate for the microorganisms to survive on. This proposal is supported by oil biodegradation and ore-stage calcite cement with delta C-13 values from -1.4aEuro degrees to -17.2aEuro degrees.
