Secondary Minerals in Soils

Using secondary minerals in Sahneh ophiolitic complex, west Iran

Kermanshah ophiolite is an extremely crushed ophiolitic complex in which a complete ophiolitic sequence is not observed. Gabbros, deloritc dikes and mostly serpentinized peridotites are among the most important constituents of these ophiolitic set. Pridotites existing in the study area are of metamorphosized types that have been severely affected by the hydrothermal solutions due to their extre...

Dating of Secondary Minerals in Nakhlites

Detecting Clay Minerals in Soils through Hyperspectral Remote Sensing

Images of representative clayey bare fields were chosen from a high spatial resolution hyperspectral dataset that was acquired with the prototypal airborne Hyper SIM-GA sensor from Selex Galileo simultaneously with ground soil spectral signatures and the collection of samples. After both the pre-processing and calibration of the SIM-GA data, the mapping procedure was developed using the 2-2.45 ...

Structural similarities of some secondary lead minerals

Some structural analogies found in tsumebite, vauquelinite, forns.cite, and brackebuschite make it possible to place these secondary lead minerMs in the s~me series with general formula Pb~MeII(Z)(XQ)(Y04), where MelI is a bivalent cation as Cu 2+ or Mn 2+, Z is the hydroxyl group or the w~ter molecule, X is S, Cr, or V, ~nd Y is P, As, or V. Some crystallochemical considerations are developed ...

Bromide Adsorp on by Reference Minerals and Soils

2010, Vol. 9 Bromide Adsorp on by Reference Minerals and Soils Bromide, Br−, adsorp on behavior was inves gated on amorphous Al and Fe oxide, montmorillonite, kaolinite, and temperate and tropical soils. Bromide adsorp on decreased with increasing solu on pH with minimal adsorp on occurring above pH 7. Bromide adsorp on was higher for amorphous oxides than for clay minerals. Shi s in point of z...
