In this study swelling problem caused by claystone containing smectite group clay mineral in Tire Lignite Enterprise (Izmir, Turkey) was investigated and triaxial swelling behavior of the claystone was determined.

Here are presented systematic measurements of the frictional properties and composition of the San Andreas Fault at 2.7 km depth, including the wall rock and active fault. We nd that the faultis weak relative to the surrounding rock and that the fault rock ...

During the past decades comprehensive investigations have been made on bentonite clays in order to find optimal components of the multi-barrier system of repositories for radioactive waste. The present study gives a mineralogical characterisation of some selected ...

<p>This paper evaluates the suitability of some smectite-rich samples from northern Patagonia (Argentina) for pharmaceutical use. The clays must comply with some general features before considering their use in pharmacy, including high mineral and chemical ...

Variations in the morphology of illitic clay minerals were observed in the Kamikita hydrothermal system for illitized smectite. Particle sizes and microtopographies were measured by transmission electron microscopy using Pt shadowing and Au decoration. Particle ...

Diagenetic illitic clays from seven North American bentonites of Ordovician, Devonian, and Cretaceous ages and from three subsurface North Sea sandstones of Permian and Jurassic ages have been examined by X-ray diffraction (XRD) and transmission and scanning ...

CHEMICAL composition. X-ray diffraction and other analytical data of a series of samples of clays that are composed essentially of illite are presented. The physical properties of these samples are given and related to variations in the composition and character ...
