Koehler, G.D., Chipley, D. and Kyser, T.K., 1991. Measurement of the hydrogen and oxygen isotopic compositions of concentrated chloride brines and brines from fluid inclusions in halite. Chem. Geol. (Isot. Geosci. Sect.), 94: 45-54. Solutions of l-5 m NaCI, KCl, CaC12 and MgC12, and synthetic brines were analyzed for hydrogen and oxygen isotopic compositions by vacuum distillation-microequilibr...

Cells of the bacterium Pseudomonas aeruginosa, which were genetically modified to produce green fluorescent protein, were entrapped in fluid inclusions in laboratory-grown halite. The bacteria were used to inoculate NaCl-saturated aqueous solutions, which were allowed to evaporate and precipitate halite. The number, size, and distribution of fluid inclusions were highly variable, but did not ap...

Evaluation of the geochemistry and hydrochemical quality of Bam salt dome located in southern Iran, was conducted in this study. Two composite samples from salt units were collected and analysed by XRD and XRF to determine their mineral and elemental compositions. Water samples were also collected from the only spring in the area and analysed for major anions, cations and some toxic elements. T...

kamtal skarn is located 15 km northeast of kharvana, east-azarbaijan. a quartz-monzonitic stock of oligocene age intruded the upper cretaceous sedimentary sequence (claystone, limestone, marl, and siltstone) developing noticeable metamorphic (marble, hornfels) and metasomatic (skarn) alteration zones along the contact. kamtal skarn is of calcic type and consists of both endoskarn and exoskarn z...

Abstract Water injection is an effective method for developing low permeability sandstone reservoirs. In the process of water flooding, reservoir damage can occur due to clay mineral content changes and it will significantly affect oil production. There are few investigations on in degree after injecting into reservoirs with different permeabilities lithologies. this study, natural cores from l...

Role of Soil Plasticity in Evaluating Clay Conditioning for EPB Tunnelling Soil clogging occurred at the early construction stage of Nanchang Metro Line 1, China, when an earth balance pressure (EPB) shield passed through the argillaceous siltstone with a total content of clay minerals of 40.5%. To avoid the reappearance of soil clogging at the later stage, a new scheme was proposed to determin...

“Coal measure gas,” excluding tight (low-permeability) sandstone gas, refers in this study to the self-sourcing unconventional natural gas stored coal, shale, and fine siltstone. It is characterized by various types of occurrences reservoirs, a distinct cyclic succession coal strata, widely distributed mosaic hydrocarbon accumulations, three configurations vertically multiple-stacked gas-bearin...
