HRTEM Interstratification Kaolinite Smectite Transformation Mechanisms
2011/12/8
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...
Mineralogical Transformation of Bioweathered Granitic Biotite, Studied by HRTEM: Evidence for a New Pathway in Lichen Activity
Back-scattered Electrons Biotite Bioweathering Granite High-Resolution Transmission Electron Microscopy (HRTEM) Lattice-Fringe Images Lichens Vermiculite
2011/12/8
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...
HRTEM investigation of microstructures in a length-slow chalcedony
HRTEM investigation microstructures length-slow chalcedony
2012/3/31
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...
