Pathways of Smectite Illitization
Clays and Clay Minerals, 1986AbstractJunction probability diagrams show variation in both composition and layer arrangement in mixed-layer clay minerals. These diagrams can represent short-range and long-range ordered, random, and segregated interstratifications. Mineralogical analyses of illite/smectite from shale cuttings, bentonites, and hydrothermally altered tuffs define ...

Hadashot Arkheologiyot - Excavations and Surveys in Israel
In July–August 2020, a salvage excavation was conducted at Giv‘at Ha-Shi t a in Yoqne‘am ‘Illit (Permit No. A-8800; map ref. 210330–430/728810–950; Fig. 1) prior to construction work. The excavation, on behalf of the Israel Antiquities Authority, was directed by T. Lang, with the assistance of Y. Yaakobi (administration), A. Kleiner (photogrammetry), E.

Clays and Clay Minerals, 1968
AbstractThe mechanism of boron uptake by clays, especially illitic clays, and the factors which control such uptake have long been debated issues. In an attempt to answer some of the questions of the controversy, three illites were treated in solutions containing boron.

Tschermaks Mineralogische und Petrographische Mitteilungen, 1956
In der dazischen Tuffitserie sudlich von Fehring finden sich mehrfach feinere, weitgehend zersetzte Einlagerungen, mit Machtigkeiten bis uber 10 m und in erheblicher Ausdehnung. Optische, elektronenoptische und rontgenographische Untersuchungen, chemische Zusammensetzung und Verhalten bei der DTA zeigen, das es sich um ein Mineral aus der Illitgruppe ...

Montmorillonite/Illite Stability Diagrams
Clays and Clay Minerals, 1984AbstractChemical activity diagrarns, prepared to illustrate the properties expected if mixed-layer mont-morillonite/illite is regarded as a solid solution, are compared to those derived from a treatment of these materials as a mixture of two phases. If the system is a solid solution, the coexisting aqueous solution should range from higher dissolved ...

Chemical Composition of Illite
SEPM Journal of Sedimentary Research, 1967Illite, as it was defined, may vary in composition over as wide a spectrum as the range of compositions of diverse detrital and authigenic micaceous minerals. From a contrasting viewpoint, however, "reference" minerals of illite have been proposed whose compositions are defined sharply, almost uniquely.
