Diagenesis of Clay Minerals from Lower Cretaceous Shales of North Eastern British Columbia
TL;DR: In this paper, a classification scheme was devised which relates variation of clay mineralogy to diagenetic stages and burial depth, based on a combination of criteria and data derived from the studies of Weaver (1961a), Kubler (1966), Burst (1969) and Dunoyer de Seconzac (1970), the upper and middle parts of the formation (upper 3250 ft) fall within the middle stage of diagenesis whereas the lower part (1000 It) is allocated to the beginning of late diagenisation.

Mineralogy and cation-exchange capacity of sediments from selected streams
TL;DR: In this paper, the authors present a plan of study for the analysis of mineralogy in terms of exchange capacity and sample treatment, and propose a method of analysis for this purpose.
Journal ArticleDOI
Biotite Flakes: Alteration by Chemical and Biological Treatment
TL;DR: Biotite alteration under acid conditions proceeds differently from the generally accepted pathway of transformation to vermiculite in which hydrated cations cause interlayer expansion, resulting in a dark-colored peripheral band on mica particles.

Heavy-Metal Nutrition and Iron Chlorosis of Citrus Seedlings.

TL;DR: Studies were made on the responses to differential supplies of copper, zinc, manganese, and iron shown by sweet orange and mandarin seedlings grown in vermiculite and solution cultures with the pH maintained near 4.5 to reduce slightly Zn toxicity in roots and to alleviate greatly toxicity due to Mn.

ION EXCHANGE IN SOILS FROM THE ION PAIRS K–Ca, K–Rb, AND K–Na1
J. Deist,O. Talibudeen +1 more
TL;DR: In this paper, a thermodynamic treatment of the exchange isotherm was applied to measure the equilibria between arable soils and mixed chloride solutions of the ion pairs, K-Ca, K−Rb, and K−Na, and the results were interpreted in terms of the standard free-energy changes of exchange reactions.
