Solubilities of corundum (Al2O3) and wollastonite (CaSiO3) were measured in H2O–NaCl solutions at 800 C and 10 kbar and NaCl concentrations up to halite saturation by weight-loss methods. Additional data on quartz solubility at a single NaCl concentration were obtained as a supplement to previous work. Single crystals of synthetic corundum, natural wollastonite or natural quartz were equilibrat...

The eastern part of the Adelaide Geosyncline contains well preserved glaciomarine sequences of the Sturtian glaciation (:750–700 Ma) including calcareous or dolomitic siltstone, manganiferous siltstone, dolostone and diamictite units and the associated Braemar ironstone facies. The ironstone facies occurs as matrix to diamictites and as massive to laminated ironstones and comprises abundant Fe ...

The mineral composition of the microbial mats at La Banya spit was studied. The spit is formed by a narrow sand bar and a peninsula and is located south of the main body of the Ebro Delta (Tarragona, Spain). Although quartz was the predominant mineral component in all sampling sites, clay, feldspars, calcite, aragonite, halite, dolomite and gypsum were also found. An increase in both the fine m...

Here, we report the draft genome sequence of Staphylococcus succinus strain CSM-77. This moderately halophilic bacterium was isolated from the surface of a halite sample obtained from a Triassic salt mine.

Abstract In this study, it is aimed to characterize the Early pliocene sandstone (EP-SD) and Late Miocene-Early Pliocene Mangaa reservoirs efficiency of their sealing cap rocks using petrographical petrophysical data these zones in northern Taranaki basin, New Zealand. The prospective potential were studied impregnated thin sections, XRD analysis, well log (self-potential, gamma-ray, sonic, den...

Fluid release from dehydration reactions is considered to have significant effects on the strength and dynamics of tectonic faults at convergent plate boundaries. It classically assumed that production fluid leads increased pore pressures perturb a fault's stress state thereby facilitates enhances deformation. This important assumption has never been supported by direct microstructural observat...

Other than halite diagenesis and organic matter degradation, Cl and Br are considered to be conservative in marine pore fluids. Consequently, Br/Cl ratios should remain constant during most diagenetic reactions. Nonetheless, Br/Cl molar ratios decrease to 1.27 3 10 ('18% less than seawater value) in pore fluids from Site 833 in the Aoba Basin of the New Hebrides convergent margin despite the la...

The 1 km thick evaporitic Permian Zechstein group in the Netherlands is subdivided into 5 halite rich sequences including K–Mg salts (polyhalite, kieserite, sylvite, carnallite and bischofite) for which position stratigraphy still poorly constrained. Understanding repartition of especially important development salt caverns require a as pure possible halite. By compiling well log seismic data o...

Bioturbation long has been ‘blamed’ for eliminating late Proterozoic-style sedimentary structures and fabrics. While the presence of diverse and complex burrows in lowermost Cambrian strata is indisputable, analysis of Precambrian– Cambrian successions in southeast Newfoundland demonstrate that this burrowing style did not produce typical Phanerozoic-style ichnofabrics. Three hundred meters of ...
