Source of diagenetic fluids from fluid-inclusion gas ratios

Characterization of gas chemistry and noble-gas isotope ratios of inclusion fluids in magmatic-hydrothermal and magmatic-steam alunite

Chemical and isotope data were obtained for the active gas and noble gas of inclusion fluids in coarse-grained samples of magmatic-hydrothermal and magmatic-steam alunite from well-studied deposits (Marysvale, Utah; Tambo, Chile; Tapajós, Brazil; Cactus, California; Pierina, Peru), most of which are discussed in this Volume. Primary fluid inclusions in the alunite typically are less than 0.2 Am...

Interpreting Geothermal Processes and Fluid Sources from Fluid Inclusion Organic Compounds and Co2/n2 Ratios

The distribution of organic species is explored using data acquired from a new dual quadrupole system that routinely measures eighteen gaseous species. The process of condensation and its affect on gas distribution is modeled, and a new discrimination diagram based on total gaseous species and the CO2/N2 ratio is introduced. We conclude that organic species concentrations indicate source; that ...

elimination of btex , voc vapors from glycol in gas hydrant unit

during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...

Germanium/silica ratios in diagenetic chert nodules from the Ediacaran Doushantuo Formation, South China

Fluid inclusion and stable isotope evidence for the origin of mineralizing fluids in south-west England

The oxygen and hydrogen isotope composition of hydrothermal fluids associated with the Variscan granites of southwest England has been inferred from analysis of various silicate minerals (predominantly quartz) and by direct analysis of fluid inclusions within quartz and fluorite. These data have been combined with the results of a fluid inclusion study to develop a model for the origin and evol...
