The mineralogical composition of soils formed on phyllite and alluvium as well as examination of their mineral weathering characteristics should provide an insight into the stage of weathering. Three soil profiles from mountain, plain and low lands were selected. Based on XRD analysis, clay fractions were dominated by chlorite–vermiculite, vermiculite, HIV, illite, mica–vermiculite or mica-smec...
متن کاملFormation mechanisms of illite, chlorite and mixed-layer illite-chlorite in Triassic volcanogenic sediments from the Southland Syncline, New Zealand
Clay minerals from the three principal kinds of zeolitic sediments from the type area for zeolite facies alteration, the Triassic Murihiku Supergroup, Southland, New Zealand, have been studied by TEM. Bentonitic tuff consists largely of smectite and heulandite with minor illite; they occur as replacements of glass shards and are inferred to be direct alteration products of tuff alteration. Both...
متن کاملکانی شناسی بخش رس و ژئوشیمی خاکهای تشکیل شده از سنگ های مادری دگرگون و آذرین قلیایی در ناحیه لاهیجان
The mineralogical and geochemical composition of the soils of three representat ive pedons fanned on basaltic andesite, andes itic basalt and phyllite were investigated. Results by XRF showed that progressive weathering of rocks have been marked by gradual accumulation of AI, Fe, Ti, Mg. H30+ and depletion of Na, K, Ca and Si in the soi l; although, predominant clay, loss and gain trend of...
متن کاملComposition Variation of Illite-vermiculite- Smectite Mixed-layer Minerals in a Bentonite Bed from Charente (france)
Mineralogical and chemical variations were studied in the upper half of a 1 m thick discontinuous bentonite bed interlaminated in the Lower Cenomanian sedimentary formations of the northern Aquitaine basin (France). X-ray diffraction patterns obtained from the <2 μm fraction in the Ca and K-saturated states were decomposed and compared to those calculated from decomposition parameters. They rev...
متن کاملMineral Chemistry of Chlorite Replacing Biotite from Granitic Rocks of the Canadian Appalachians
Chlorite flakes, as a product of alteration of biotite, the dominant ferromagnesian mineral in the Paleozoic granitic rocks of the Canadian Appalachians, have been analyzed by electron microprobe for major elements and by 57Fe M?ssbauer spectroscopy for the coordination and oxidation state of Fe. Comparison of M?ssbauer Fe3+/Fe ratios obtained from chlorite and its host biotite indicates that c...
