Clays occur in many different geological environments: weathering crusts and soils, continental and marine sediments, volcanic deposits, geothermal fields, wallrock alteration produced by intrusion of plutonic rocks and hydrothermal fluids, and very lowgrade metamorphic rocks.
Orographic precipitation on the southern flank of the southeastern Koolau Mountains produces a pronounced precipitation gradient. The corresponding gradient in the intensity of the chemical weathering environment provides an opportunity to address the effects of varying chemical weathering intensity on the composition of claysize weathering products in soils developed on basalt.

On the other hand, those interstratified clay minerals that are generally associated with diagenesis which include regularly interstratified, partially ordered and randomly interstratified illitesmectiteconsist of extremely fine particles that are typically some tens of Angstroms in thickness.

A number of commercial bentonite deposits occur in Çankiri Basin of interior Anatolia, Turkey. Our observations suggest that these olivegray clays are produced by sedimentary processes from the reworking of pyroclastic rocks of the Late Miocene age and deposition of detritic materials in a lacustrine environment. Leaching of ultramafic components of the Cretaceous Ophiolitic Melange, which ...
Source areas of illitevermiculite mixed layers Illitevermiculite mixed layers occur in recent Formation of vermiculite and vermiculitic northwestern Atlantic sediments, the clay fraction mixed layers through weathering of which is dominated by illite and chlorite The origin of interstratified clay minerals such as (Biscaye, 1965; Hathaway ...
Conversely, randomly interstratified structures have nonintegral peaks at positions intermediate between the peaks from the individual mineral layers. For example, randomly interstratified illitechlorite would be characterized by a 001 basal diffraction peak between 10 and 14 angstroms.
A third mineral phase The decrease in Mg and Fe content is also well ex was also collected from the coarse clays: a randomly plained by the preferential weathering of the Fe, Mg interstratified mica/chlorite mineral for which the heat rich chloritic layers.
Xray diffraction studies of the weathering residues and the sulfate efflorescences have also identified dioctedral and ctedral illite, kaolinite, vermiculite, and an 11 12 Å phase, thought to be a type of randomlyinterstratified biotitevermiculite.

The physicalchemical properties of clay minerals are extremely sensitive to changes in the PTX conditions. Therefore, most of the minerals used as catalysts in experimentation on organic materials are transformed during the experiments. However, the structure and crystalchemistry of run products ...
