Abstract: The evolution of texture, structure and chemical composition of chloritic clays in coeval pairs of metabasites and metapelites of a prograde sequence from the Bükk Mountains has been investi...
Abstract: The distribution and crystal-chemical characteristics of chlorite, corrensite, and mica in samples from a stratigraphic profile in the Cameros basin are controlled by changes in the sediment...
Abstract: A new method is proposed for applying the chlorite geothermometer using X-ray diffraction (XRD) data. A linear correlation has been found between the (001) basal spacing of chlorite and its ...
Chromian clinochlore-IIb-4 (triclinic) and IIb-2 (monoclinic) polytypes from the Day Book Body, North Carolina, were heated to 650 ?C for 5 hours and air quenched. Single-crystal X-ray refinements o...
To elucidate the process and mechanism of the prograde conversion of saponite to chlorite through corrensite, the microstructures of a series of chlorite-smectite (C-S) mixed-layer samples from Kamik...
Clay mineralogical X-ray diffraction and electron microprobe studies have been carried out on separated <2 ?m fractions from cutting and core material from three wells in the Chipilapa geother- mal ...
Abstract: Transmission electron microscopy/analytical electron microscopy (TEM/AEM) were utilized to study pyrite and sphalerite inclusions in chlorite or mixed-layer chlorite-corrensite from an analc...
Abstract: The chemical composition of hydrothermal chlorite was determined by means of more than 200 electron microprobe analyses (EMPA) in almost all of the 70 chlorite-bearing samples taken from 5 b...
Abstract: Oxygen isotopic compositions were determined for coexisting mixed-layer serpentine-chlorite (Sp-Ch) and illite-smectite (I-S) from 5 Tuscaloosa Formation sandstone cores sampled between 1937...
This paper demonstrates that the six standard polytypes of chlorite, whose definitions are based on the orientation of the interlayer sheet and the position of the interlayer sheet on the 2:1 layer, c...
The structure and formation mechanisms of low-angle grain boundaries (LAGB) in chlorite have been investigated using HRTEM to resolve each cation sheet in chlorite. The LAGB are abundant in two hydrot...
Atomic-resolution transmission electron microscope (TEM) images reveal that IIbb( b5 978 ) Mg,Al,Fe-chlorite from Koongarra, Australia, transforms to vermiculite via a range of intermediate chemical a...
Abstract: The clay fraction of a Spodosol and its parent rock in the Apennine mountains of central Italy were studied by powder X-ray diffraction (XRD) and infrared (IR) spectroscopy, to evaluate the ...
Abstract: Vesicular and groundmass phyllosilicates in a hydrothermally altered basalt from the Point Sal ophiolite, California, have been studied using transmission electron microscopy (TEM). Pore-fil...
Transmission electron microscopy (TEM) , analytical electron microscopy (AEM), and decomposition-simulation of X-ray diffraction (XRD) patterns were used to characterize trioctahedral clay from Sanc...
