Wildfires and prescribed fires burn many thousand of hectares of forest annually (Ulery et al., 1996). The intensity of forest burning is related to weather conditions, amount of fuel available and th...
As we know, agricultural waste like rice husk & straw etc., are produced a lot from the rice paddy special caution is needed in order to prevent the resulting serious environment pollution. Due to lac...
Abstract: Nordstrandite from Lages represents the first occurrence of this mineral in an oxisoil that does not involve the influence of a calcareous substrate. This is also the first reported occurren...
Abstract: Intercalation of amino acids into 10.0-Å hydrated kaolinite was studied by powder X-ray diffraction (XRD), differential thermal analysis-thermal gravimetry (DTA-TG), and infrared (IR) ...
Abstract: Many soils developed from volcanic rocks in southern Brazil exhibit spontaneous magnetization caused by the presence of fine-grained maghemite (γ-Fe2O3), but few attempts were made to quanti...
Burbankite, ideally (Na,Ca) (Sr,REE,Ba) (CO ) , is a rare REE carbonate mineral that until now had been encountered only at a few localities including highly alkaline silicate rocks, carbonatites, a...
Lower Wham Brake is a cypress, rim-swamp artificially enclosed in 1950 as a 22 km2 industrial reservoir by the International Paper Company (IPC)-Bastrop Mill, for regulating downstream water quality. ...
The smectite-to-illite conversion during shale diagenesis has recently been used to constrain the estimate of a basin's thermal history. We have systematically investigated the kinetics for the conver...
Weathered perthite and mixed muscovite-kaolinite from a kaolinitic granite at Trial Hill in east Queensland and kaolinized sericitic alteration from a granite from the Ardlethan Tin Mine of New South ...
A kaolinite-pyridine intercalation compound was prepared using hydrated kaolinite as an intermediate. Hydrated kaolinite having a basal spacing of 10 侌 was treated with pyridine to form a well-ordered...
Montmorillonite-based catalysts were compared with an acidic ion-exchange resin of the type used industrially for the production of methyl t-butyl ether (MTBE) from methanol and isobutene or t-butanol...
The Rokle bentonite deposit is part of an accumulation of argillized volcanoclastic rocks in the Tertiary stratovolcanic complex of the Doupovsk?Mountains east of Karlovy Vary (Carlsbad), about 100 km...
Simple equations are presented which allow double-layer potentials of clays to be derived from co-ion exclusion measurements in monovalent and divalent electrolyte solutions. These equations have been...
The sand and silt fractions of soils derived from Tertiary basalt in northeastern Ireland exhibit unusually high cation-exchange capacities. Smectite was identified by X-ray powder diffraction in all ...
The effects of NaOAc removal of carbonates, H2O2 removal of organic materials, and sodium citrate-bicarbonate-dithionite (SCBD) removal of iron oxides upon the X-ray powder diffraction (XRD) character...
