Preferred Orientation of Phyllosilicates in Gulf Coast Mudstones and Relation to the Smectite-Illite Transition
Gulf Coast Phyllosilicates Preferred Orientation Smectite-Illite Transition
2011/12/7
Abstract: Development of preferred orientations of illite-smectite (I-S) has been studied using X-ray diffraction (XRD) texture goniometry to produce pole figures for clay minerals of a suite of 16 mu...

Abstract: Sediments from depths to 670 m in the Barbados accretionary complex and transecting the décollement zone have been studied by transmission and analytical electron microscopy (TEM/AEM). The s...
Hydrothermal Treatment of Smectite, Illite, and Basalt to 460°C: Comparison of Natural with Hydrothermally Formed Clay Minerals
Basalt Berthierine Hydrothermal Illite Smectite Stability
2012/1/11
Wyoming bentonite, Fithian illite, and basalt from the Umtanum Formation, Washington, were treated hydrothermally at 200° to 460°C and 260 to 500 bars for 71 to 584 days. No change was detected for th...
