Hadashot Arkheologiyot - Excavations and Surveys in Israel, 2012
During May 2011, a trial excavation was conducted at the site of Trigonometric Point 968 west of Yoqne'am 'Illit (Permit No. A-6189; map ref. 20721-99/72667-738), prior to construction. The excavation, undertaken on behalf of the Israel Antiquities Authority and underwritten by the

Science, 1965
The average potassium oxide content of 18 Paleozoic two-layer monoclinic illites is 8.75 percent. There is an excellent linear relation between the ratio of the intensities of the reflections at 10 angstroms and 5 angstroms (10 Å/5 Å) and the potassium oxide content.

EXPERIMENTAL STUDIES OF ILLITE
Clays and clay minerals (National Conference on Clays and Clay Minerals), 1958AbstractInvestigations in the system K2O-MgO-Al2O3-SiO2-H2O were made in an attempt to synthesize micas similar to illite and to determine their upper stability limits. These are representative of materials referred to by many clay mineralogists as illite, hydromuscovite and K-bentonite.

Hadashot Arkheologiyot - Excavations and Surveys in Israel, 2007
During February-March 2005 a salvage excavation was conducted on the southeastern fringes of Horbat 'Illit (Permit No. A-4385*; map ref. NIG 2030/6187; OIG 1530/1187), following an archaeological survey in the region carried out by A. Nagorski and H.

Soil Science Society of America Journal, 1971
Abstract Equilibrium solubilities of the 0.2–2.0µ size fraction of three K + ‐saturated illites were determined in high‐pH aqueous solutions. Beavers Bend, Fithian, and Goose Lake illites were selected for the study. Solubility products were found to be 10

The geology of illite is surprisingly diverse since it forms in soil as well as in metamorphic or peri-magmatic conditions. The goal of this chapter is to give an overview of this diversity in order to outline the most important facts concerning illite formation.

Clays and clay minerals (National Conference on Clays and Clay Minerals), 1964
Abstract 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 ...

Retarded illite crystallinity caused by stressinduced sub-grain boundaries in illite
Clay Minerals, 2000AbstractAn XRD-TEM study was carried out on low-grade metapelites (Transantarctic Mountains) to determine the cause of apparent inconsistences in grade as determined by IC and independent geologic relations. The illite crystallinity (IC) data indicate that the three units investigated (BT, RBT, MS) were affected by very low- (IC = 0.24°Δ2θ in BT) to ...

Phase relations among smectite, R1 illite-smectite, and illite
American Mineralogist, 1997A variety of smectitic and illitic clays were studied by TEM and AEM, following ex- pansion by L.R. White resin, to define phase relations for clay minerals undergoing di- genesis and low-grade metamorphism. Samples included a prograde shale sequence from the Gulf Coast, a hydrothermal bentonite from Zempleni, Hungary, and shales from the Nankai Trough,

The Charge of Component Layers of Illite-Smectite in Bentonites and the Nature of End-Member Illite
Clays and Clay Minerals, 2009AbstractThe nature of component layers of mixed-layer illite-smectite and their possible evolution in the course of illitization have been debated since the 1960s. The present study is a new attempt to solve these problems, using samples collected from diverse geological formations around the world.
