Abstract

Calcite and quartz veins in the gabbroic and dunite rocks of the Semial ophiolite (UAE) were selected for fluid inclusion analysis. The inclusions contain both aqueous low-salinity and hydrocarbon-dominated fluids. Microthermometry data indicate that the aqueous fluids contain 0.22 to 1.45 equivalent wt% NaCl and occasionally contain traces of hydrocarbons. Homogenization to liquid occurred between 91 and 152°C. Modeling based on these fluid inclusion observations indicates that the trapping conditions of the studied rocks were subjected to temperatures of 162 and 172°C, occasional pressures of 610-710 Pa and the sequence percolation of aqueous and hydrocarbon fluids.
