Abstract: Transmission electron microscopy (TEM) observation shows narrow regions in a Ti-containing Mg-rich annite of composition (K0.90Na0.02)(Mg0.72Fe2+1.78Mn0.03Ti0.27Al0.05)(Si2.77Al1.23)O10(OH,F...
Ordering of the stacking sequence in cookeite with increasing pressure: An HRTEM study
Ordering stacking sequence cookeite increasing pressure HRTEM study
2012/4/5
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...
Smectite-to-Illite Conversion in a Geothermally and Lithologically Complex Permian Sedimentary Sequence
Burial diagenesis Contact metamorphism Lithology Paleotemperature Vitrinite reflectance
2011/12/1
The <0.5-祄 fraction of 120 samples from a lithologically complex Permian sedimentary sequence, underlying dolerite intrusive sheets, has been characterized by means of X-ray diffraction to establish I...
Structural Variations in Chlorite and Illite in a Diagenetic Sequence from the Imperial Valley, California
Chlorite Diagenesis High-gradient magnetic separation Illite Interstratification Polytype X-ray powder diffraction
2012/1/4
Samples of cuttings from the Borchard A-2 well, Imperial Valley, California, were collected over a measured borehole temperature interval 135° to 275°C. The <0.5-µm (e.s.d.) fraction was separat...

Weathering of Enstatite to Talc Through a Sequence of Transitional Phases
Biopyribole Enstatite Smectite Talc Transmission electron microscopy Weathering
2011/11/23
Abstract: Orthopyroxene (En85) weathers initially by vacancy diffusion, and through this process hydration occurs and a sequence of biopyriboles develops, culminating in a talc-like layer silicate who...
The Influence of Hydroxyl Orientation, Stacking Sequence, and Ionic Substitutions on the Interlayer Bonding of Micas
Hydroxyl Orientation Stacking Sequence Ionic Substitutions Micas
2012/2/13
Hydroxyl orientation has a major influence on the strength of the ionic interlayer bonding in micas because of the strong repulsion between the hydrogen and the interlayer cation (IC). In order to det...
