Characterization of mixed-layer illite-smectite from bentonites using microscopic, chemical and X-ray methods: Constraints on the smectite-to-illite transformation mechanism
Characterization mixed-layer illite-smectite microscopic X-ray methods smectite-to-illite transformation mechanism
2012/3/31
We studied mixed-layer illite-smectite (I/S) (,1 or 0.5 mm size fractions) in 28 diage-netic bentonite samples, Pliocene to Ordovician in age, from different locations in North America and Europe to i...
Comparison of Structural Models of Mixed-Layer Illite/Smectite and Reaction Mechanisms of Smectite Illitization
Illite Illite/Smectite Mixed-Layer Reaction Mechanism Smectite
2011/12/22
Abstract: This paper compares mechanisms of the reaction of smectite to illite, in light of structural models for interstratified illite/smectite (I/S). The crystal structure of I/S has been described...
Some Evidence Supporting the Existence of Polar Layers in Mixed-Layer Illite/Smectite
Differential Thermal Analysis Mixed-layer illite/smectite Polar layer
2011/12/28
The fraction <20 祄 of a bentonitic material was selected to study the transformation of smectite into illite under hydrothermal conditions. Powder XRD showed that the studied material was composed of ...

2012/1/11
The reaction of smectite to illite in shale from the COST 1 well in the south Texas Gulf Coast and from altered ash-fall tufts from the Morrison Formation in New Mexico was investigated using X-ray po...
Mixed-Layer Illite/Smectite Minerals in Tertiary Sandstones and Shales, San Joaquin Basin, California
Carbonate cementation Illite/smectite Microprobe analysis Mixed layer Smectite Time-temperature index
2012/1/11
The southern San Joaquin Valley contains more than 7 km of sedimentary fill, largely Miocene and younger in age. Ancient depositional environments ranged from alluvial fans at the basin margins to tur...
