-Radium sorption efficiencies as a function of temperature, Ra concentration, and secondary mineral sorbate were determined in a 0.0! M NaC1 solution. Radium sorption on a characterized clinoptilolite, montmorillonite, nontronite, opal, silica gel, illite, kaolinite, and glauconite under comparable experimental conditions allowed determination of Ra sorption efficiency curves for each, through ...

The Main Glauconite Bed (MGB) is a pelleted greensand located at Stone City Bluff on the south bank of the Brazos River in Burleson County, Texas. It was deposited during the Middle Eocene regional transgression on the Texas Gulf Coastal Plain. Stratigraphically it lies in the upper Stone City Member, Crockett Formation, Claiborne Group. Its mineralogy and geochemistry were examined in detail, ...

The oil and gas industry plays a key role in the Russian economy. However, its risks of environmental impact are among highest modern production industries. need for fastest recovery territories requires prompt elimination consequences soil pollution with oil. This might be achieved by an extensive complex technologies, including biotechnological product application. study examined contaminated...

Sampling of six horizons quartz-glauconite sands in Kaniv dislocations Ukraine yielded more than three thousand vertebrate specimens, including elasmobranch teeth, chimaera dental plates, actinopterygian and sauropsid teeth bones. Our study represents the first illustrated detailed description from Ukrainian Albian deposits since Rogovich (1861), whose specimens were still preserved collections...

Abstract Agromineral resources are minerals and rocks used to improve soil productivity health. These can be applied: indirectly, by extracting concentrating one or more industrial processes for the production of conventional, highly soluble fertilizers; directly, without processing, except fine grinding, direct application. include sedimentary phosphates, limestones/dolostones, potash glauconi...
