Smectite to illite transformation of Gulf of Mexico -Eugene Island (GoM-EI) mudrock
… to look at the relationship between smectite-to-illite transformation and overpressure generation. The proposed research has two phases. Phase one objective is to study the reaction rate and the conditions such as temperature, time, KCl concentration that induce smectite-to-illite transformation. …

Smectite/Illite Distribution and Diagenesis in the South Timbalier Area, Northern Gulf of Mexico
… by XRD, is primarily mixed-layer smectite and illite with a minor amount of kaolinite. The mixed-layer mineralogies are end-member smectite, mixed-layer smectite, mixed-layer illite, and end-member illite. These clay mineral fractions do not correlate with age. The illite mixed layer percentage …

DESORPTION OF COPPER FROM ILLITE CLAY USING A CHELATING RESIN ENCAPSULATED BETWEEN POROUS MEMBRANES
… the release characteristics of trace metals, illite clay was "contaminated" with known amounts of trace metals and suspended in aqueous solutions. Continuous agitation was provided. As the cassette removes metal from solution, the clay is driven by equilibrium considerations to desorb more …

Argillic Alteration Associated With the Amethyst Vein System, Creede Mining District, Colorado (Illite, Smectite)
The Amethyst Vein System is an epithermal Ag-Pb-Zn-Cu-Au deposit in the Creede mining district, southwest Colorado. Silicification and argillization are the two dominant facies of hydrothermal alteration associated with the deposit. Most silicification occurs in the intermediate and deep levels of …

Illite in the Lower Paleozoic of the Illinois Basin: Origin, age, and polytype quantification
Illite was first named in 1937 in Illinois by Ralph Grim, one of the founders of clay mineralogy. Illite is the most abundant clay mineral on the earth's surface. However, we know very little about the origin of illite in Illinois. This dissertation focuses on two aspects of illite in the Lower …

Sorption Characteristics of Veterinary Ionophore Antibiotics Monensin and Lasalocid and Soil Clay Constituents Kaolinite, Illite and Montmorillonite
… desorption capabilities were not observed.</p><p>Illite (ILL) had optimal adsorption conditions for and showed strong affinity for both LAS and MON. Desorption was very high in the competitive study. Kaolinite (KAO) showed moderate adsorption and desorption was nearly twice as high when the …

Petrographic, Fluid Inclusion, and Illite Geothermometry Analysis of the Rumpel Lake Drill Core, Athabasca Basin, Northern Saskatchewan, Canada
… fluids using petrographic, fluid inclusion, and illite geothermometric methods on samples from the Rumpel Lake drill core, and to compare the results with other barren areas in the Athabasca Basin. The Rumpel Lake drill core contains five formations from within the Athabasca Group (from oldest to …

Clay mineral formation and fluid-rock interaction in fractured crystalline rocks of the Rhine rift system : case studies from the Soultz-sous-Forêts granite (France) and the Schauenburg Fault (Germany)
… of clay mineral assemblages. It evaluates the argillite mineralizations along faults and fracture zones at key tectonic positions in relation to the upper Rhine graben rift structure and assesses the timing and episodic nature of clay mineral formation that occurred within both the buried basement …

Clay petrology of Mesozoic to recent sediments of central western North Island, New Zealand
… The predominance in the same samples of illite and chlorite in coarser fractions but of montmorillonite and kaolinite in finer fractions emphasises that the geologic interpretation of clay mineral distributions in sediments may be significantly influenced by the grain size fraction chosen …

The Semliki Basin, Uganda : its sedimentation history and stratigraphy in relation to petroleum accumulation
… feldspars and calcite. The clay minerals include illite, illite-smectite, kaolinite, montmorillonite, illite-monnnorillonite, and mica with mixed layer illite-smectite and illite layers dominating. The clay minerals in the sediments were interpreted to be as a result of weathering of feldspars and …

Roles of Nano- and Micro-Scale Subsurface Geochemical Reactions on Environmentally Sustainable Geologic CO2 Sequestration
… model clay mineral. We observed numerous fibrous illite precipitates on mica after reaction for only 3 h, which had not been previously reported. A few hours later, the mica surface cracked and fibrous illite detached. The mobilization of fibrous illite can decrease the aquifer's permeability …

Studies of clay minerals and their decomposition products
… of five coals revealed the presence of pyrite, illite, kaolinite and Quartz, together with other minor phases. Analysis of the coal ashes indicated the formation of hematite and an Fe (3+) paramagnetic phase, the latter resulting from .the dehydroxylation of the clay minerals during ashing at …

Mineralogy and geochemistry associated with hydrothermal alteration of a rhyolitic hyaloclastite from Ponza Island, Italy
… propylitic zone is characterized by mixed-layer illite/smectite (I/S) with 10 to 85% I, mordenite, opal-C, and authigenic K-feldspar (akspar). The silicic zone is characterized by I/S with $\ge$90% I, pure illite, quartz, akspar, and occasional albite. In the sericitic zone the hyaloclastite …

A study of the effects of organic matter on illitization in the Woodford Shale, Oklahoma and Kansas
… yet most clay mineral studies report primarily illite (Caldwell, 2011 & Whittington, 2009). A previous report contrasts this behavior to other late Paleozoic shales in Oklahoma (Kowal, 2016). The major difference between these units is the amount of organic matter, which is much higher in most …
