Physico-chemistry of continental bentonites and kaolin for ceramic applications.
The Role of Extensional Fractures and Quartz Veins in the Formation of Kaolin Deposit From the Dwyka Tillite in Grahamstown, Eastern Cape Province, South Africa.
Phase Transformations Associated with Thermal Decomposition of Duthuni Kaolin, South Africa.
The aim of this work is to characterize a refractory elaborated with a kaolin extracted from Djebel Debbagh (Algeria). This clay contains essentially 38.5% (in mass) of alumina and 40% of silica. The ...
Kaolin Deposits and Occurrences in Africa: Geology, Mineralogy and Utilization.
Kaolin deposits, situated approximately 20 km south of Hisarcık, have been formed by the alteration of dacite and dacitic tuffs related to the Miocene volcanism associated with extensional tecton...
Granulometric evaluation of continental bentonites and kaolin for ceramic applications.
Crystal morphology and indicative microchemistry of kaolinite from kaolin occurrences in Alkaleri region, northeastern Nigeria.
Abstract: The clay particles in a kaolin deposit from Brazil were investigated by X-ray diffraction (XRD), differential thermal analysis (DTA), analytical transmission electron microscopy (ATEM), and ...
Abstract: The Madayi clay deposit consists of a thick sequence of residual white kaolinitic clay underlying the sedimentary Warkallai Formation, which includes gray carbonaceous kaolinitic clays, lign...
Abstract: Six kaolin samples from the Lower Tertiary Huber Formation near Wrens, Georgia were analyzed using transmission electron microscopy (TEM), electron diffraction (ED), powder X-ray diffraction...

Abstract: The residual kaolin deposits near Lastarria, South-Central Chile, were formed by weathering of subvolcanic quartz porphyry stocks, which intruded the metamorphic basement of the Coastal Cord...
Abstract: Clay mineral compositions from 2 paleosol profiles (Chu-Wan, CW, and Shiao-Men Yu, SMY, profiles) on the late-Miocene sediments in Penghu Islands (Pescadores), Taiwan, are characterized by r...
Abstract: Hisingerite, first described in 1810, has been variously regarded as noncrystalline, as a septechlorite, as ferric allophane, as ferric halloysite and as poorly crystalline nontronite. Hisin...
