Abstract. The emergence of desiccated lake bed sediments and their exposure to wind erosion as a consequence climate change drought in arid semiarid regions the world poses growing hazard. Airborne dust originating from such soils can create health environmental issues due high salt content presence toxic elements. aim present study is twofold, namely investigate newly emerged playa surfaces we...

Due to their widespread availability, sandstones are commonly used as a natural stone for buildings, monuments and sculptures. In thecurrent study, nine sandstone samples from the Upper Red Formation (specified by the letters A, B, C, CG, S, S1, Sh, Tr and Min)were studied from a petrophysical point of view and their durability was evaluated. Then, their suitability as building stones wasassess...

Landslides in tropical and sub-tropical regions are generally associated with weathered rock profiles which often possess chemical and mineralogical heterogeneities at materialand mineral-scales. Such heterogeneities reach a climax by the occurrences of oxyhydroxideand clayrich zones. Weakness and low permeability of these zones makes them ideal for the development of slip zones along which lan...

-Multivariate statistical analyses of geochemical, mineralogical, and cation-exchange capacity (CEC) data from a Venezuelan oil well were used to construct a model which relates elemental concentrations to mineral abundances. An r-mode factor analysis showed that most of the variance could be accounted for by four independent factors and that these factors were related to individual mineral com...

solution potassium (so-k) and exchangeable k (ex-k) extracted by nh4oac are the major sources of potassium used by plants, but initially non-exchangeable k (nex-k) can also contribute significantly to plant uptake. perennial ryegrass (lolium perenne, cv. roper) was successively planted in ten surface soil samples with different clay mineralogical composition belonging to five soil types to dete...

this work aims to extract the mineralogical constituents of the lahroud hyperion scene situated in the nw of iran. like the other push-broom sensors, hyperion images suffer from spectral distortions, namely the smile effect. the corresponding spectral curvature is defined as an across-track wavelength shift from the nominal central wavelength, and alters the pixel spectra. the common “column me...
