Discovery of abundant anhydrite (CaSO4) and gypsum (CaSO4W2H2O) in the otherwise carbonate sediment comprising the upper 3 km thick layer of the target rock at the K/T impact site has prompted research on these minerals. Evaluation of the severity of the proposed extinction mechanism involving injection of impact-generated SO2 and SO3 into the stratosphere entails determination of criteria for ...
Single-distilled water encapsulated in graphene pockets has been studied by aberration-corrected high-resolution transmission electron microscopy and electron energy loss spectroscopy at an acceleration voltage of 80 kV. Inside the graphene pockets, crystallization and in situ crystal growth are reported and identified as the insoluble AII phase of CaSO4 (anhydrite) in a quasi-two-dimensional s...
The technology for obtaining hydrofluoric acid and the peculiarities of its production were studied, physical chemical properties waste examined. Activators that accelerated hardening anhydrite binder selected. process recycling fluorine hydrite from at Ulba Metallurgical Plant JSC was unburnt with a setting time 30 min obtained. On basis obtained data, technological scheme developed. effective...
The Fatha Formation, formerly known as the Lower Fars was deposited in a shallow basin, southern Iraq during Middle Miocene. By using description of cores, we found large heterogeneity lithology; contains mixing limestones, mudstone, marl, marly limestone, sandstone, and gypsum, or anhydrite. In this study, Formation divided into three main units according to lithofacies, namely, marl-anhydrite...
