Diagenesis of the Sedimentary Fe–Ni Deposits of Euboea: Evidence Based on Phyllosilicate Mineralogy
A set of samples with different textures from the sedimentary Fe–Ni deposits of Central Euboea, Greece, were studied with XRD and SEM-EDS to investigate the relationships between phyllosilicates present.

Charge Heterogeneity in Smectites
AbstractThe heterogeneity of sites for Ca→K exchange was examined by microcalorimetry in the <0.2-μm fractions of some selected smectites. Six groups of sites, ranging in exothermic exchange enthalpy (-d(ΔHx)/dx) from 5.7 to 10.9 kJ/eq were identified.

Natural Mordenite from Spain as Pozzolana
This work deals with anomalous concentrations of natural mordenite in the southeast of Spain. The X-ray diffraction (XRD) and scanning electron microscopy (SEM) studies evidenced that the samples contain mainly monomineral zeolitic phase of mordenite (70%

Weathering microenvironments on feldspar surfaces: implications for understanding fluid-mineral reactions in soils [PDF]
The mechanisms by which coatings develop on weathered grain surfaces, and their potential impact on rates of fluid-mineral interaction, have been investigated by examining feldspars from a 1.1 ky old soil in the Glen Feshie chronosequence, Scottish ...

Sorção de Diuron em minerais da fração argila
The objective of the present study was to evaluate the adsorption of the herbicide Diuron onto smectite and Fe oxides minerals. Ninety mg of each mineral, 1 mL of 0.15 mol L-1 CaCl2 and 8 mL of Diuron (0.25-10.00 mg L-1) were used in triplicates.
