AbstractThe microbial diversity of production waters of five Tunisian oilfields was investigated using Single Strand Conformation Polymorphism (SSCP) technique followed by cloning‐sequencing. Dynamics of bacterial populations in production waters collected from four wellheads were also evaluated.

Geodynamic setting of mesothermal gold deposits: An association with accretionary tectonic regimes
Geology, 1990Mesothermal gold provinces of Phanerozoic age are characteristically associated with regional structures along which allochthonous terranes have been accreted onto continental margins or arcs. A recurring sequence of transpressive deformation, uplift, late kinematic mineralization, and shoshonitic magmatism is consistent with thermal reequilibration of

Microbiology, 2019
Phototrophic communities forming in the bottom of the Berikei highly mineralized mesothermal sulfide springs (Kayakent region, Dagestan, Russia) were investigated. The Berikei springs are an interesting example of combined effect of such factors as temperature, salinity, pH, and sulfide of occurrence and structure of phototrophic microbial communities.

Electron–Ion Coupling in Mesothermal Plasma Beam Emission: Full Particle PIC Simulations
IEEE Transactions on Plasma Science, 2012Full particle particle-in-cell simulations are performed to study the collisionless electron-ion coupling during ion beam emission and neutralization. Simulations show that ion beam neutralization and propagation are two closely coupled processes. Electron-ion coupling is achieved through interactions between the trapped electrons and a potential well ...

Compositions of microbial communities associated with oil and water in a mesothermic oil field
Antonie van Leeuwenhoek, 2011Samples of produced water and oil obtained from the Enermark field (near Medicine Hat, Alberta, Canada) were separated into oil and aqueous phases first gravitationally and then through centrifugation at 20°C in an atmosphere of 90% N(2) and 10% CO(2).

Deformational controls on the dynamics of fluid flow in mesothermal gold systems
Geological Society, London, Special Publications, 1999Abstract Coupling between deformation processes and rock permeability is a major factor influencing fluid migration and fluid-rock interaction during the formation of mesothermal lode gold systems in mid- to upper crustal regimes. The evolution of permeability during deformation is controlled by a dynamic competition between deformation ...

Rapid dewatering of the crust deduced from ages of mesothermal gold deposits
Nature, 1991THE large-scale migration of fluids through the continental crust has been well documented, but there is no consensus regarding the timing of fluid migration relative to orogenic episodes, or rates of crustal dewatering1. Here we present40Ar/39Ar dates for muscovites from quartz veins along a major shear zone in southeast Alaska, which show that the ...

Origin of Pan-African mesothermal gold mineralisation at Bin Yauri, Nigeria
Journal of African Earth Sciences, 2000Abstract In the Bin Yauri area, mesothermal Au-sulphide-quartz-carbonate veins and associated hydrothermal alteration appear to have accompanied late tectonic brittle faulting which cut across the contact zone of a Pan-African granodiorite batholith intruding phyllites.
