Formation 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 کاملA Proposed Phase Diagram for Illite, Expanding Chlorite, Corrensite and Illite-montmorillonite Mixed Layered Minerals
-New and published experimental data on hydrothermally treated (2-kbar water pressure, 300-400~ natural clay minerals is used to construct phase diagrams in composition and pressure-temperature space which define the phase relations of mixed layering solid solution in dioctahedral (illitemontmorillonite) and trioctahedral expanding chlorite and corrensite-like minerals. Three major relations ar...
متن کاملEXAFS Study of Sr sorption to Illite, Goethite, Chlorite, and Mixed Sediment under Hyperalkaline Conditions.
Strontium is an important contaminant radionuclide at many former nuclear sites. This paper investigates the effect of changing pH and ionic strength on the sorption of Sr to a range of common soil minerals. Specifically it focuses on the sorption of Sr onto illite, chlorite, goethite, and a mixed sediment. The interplay between ionic strength and pH was determined by varying the background ion...

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...
