-X-ray powder diffraction (XRD) patterns for many interstratified mica/glycolated smectites were calculated by changing combinations of probabilities and transition probabilities of two-component layers. Three basal XRD reflections, 5.1L7.6~ (P l), 8.9 ~ 0.2~ (P2), and 16.1~176 (P3) were selected for the quantification curves. A distinct relationship exists between a20~ (p2 Pl) and A202 (P3 -P2...

The objective of this study was to investigate the clay mineralogy of soils derived from different parent materials in Binaloud zone, western Mashhad. Two soil profiles on the summit of granitic, ultrabasic and metamorphic rocks were described and sampled from genetic horizons. Clay fraction of the soils was analyzed using X-ray diffraction method. Chlorite, smectite, mica, amphibole and regula...

Pedogenesis and clay mineralogy of soils and rock samples were studied in a transect of calcareous, gypsiferous, saline soils and sediments of Bakhtegan lake bank in southern Iran. The main objectives of study were to determine the occurrence of clay minerals and factors controlling their distribution pattern and relative abundance in soils and parent materials. The soil parent material is high...

-The alteration experiments of phlogopite with 0.01 N HC1 solution containing 0.1 M NaC1 at 50*, 80* and 120"C have been carried out to aid in the understanding of the dissolution process of mica and the formation of secondary phases such as vermiculite and interstratified mica/vermiculite. Twenty milligrams of phlogopite samples were suspended in 20 ml or 100 ml of leaching solution. In these ...

We present two computing tools, ClayTherm and ISTherm, devoted to the estimation of thermodynamic properties both anhydrous hydrated clay minerals (ClayTherm), illite/smectite (I/S) mineral series (ISTherm). The first tool, ClayTherm, is property estimates for minerals. It combines several previously published models, including hydration aspects. Verification provided, against a set solubility ...
