Abstract: It is shown that polytypes or stacking sequences of cronstedtite, an Fe-bearing trioctahedral 1:1 phyllosilicate, can be determined using near-atomic high-resolution transmission electron mi...
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...

Abstract: The transformation of smectite into kaolinite and kaolinite-smectite interstratification were studied in samples belonging to the Argiles Plastiques formation of the Paris basin, by high-res...
Abstract: The question of whether clay minerals can be biogenically transformed as a result of lichen activity at the lichen-rock interface remains unresolved. We applied several microscopical and ana...
High-resolution transmission electron microscopy reveals dense Brazil-twin boundaries on the unit-cell scale in length-slow chalcedony. The twins can be considered as the result of stacking of left- a...
Microcrystalline opal wasinvestigated using low-dose transmission electron microscopy (TEM) methods to identify microstructural characteristics and possible phase-transforma-tion mechanisms that accom...
Fundamental particle thickness measurements of Dolná Ves hydrothermal illite/smectite (I/S) samples confirmed earlier findings regarding the content of fixed cations in illite interlayers (ca. 0.9/O10...
Synchrotron radiation, high-resolution transmission electron microscopy (HRTEM),X-ray powder diffraction, and Raman spectroscopy wereused to study the structure and thermal behavior of malayaite, CaSn...
To explore the effect of pressure on the stacking-sequence of the chlorite cookeite, a systematic TEM study ofstacking microstructures has been conducted onnatural samples from pegmatitic and metamorp...
Young marine green grains, from Fe-rich sediments, were studied by using HRTEM systematically combined with punctual microchemical EDX analyses. Experimental results demonstrated these grains were mad...
