Alga-Like Fossils from the Early Precambrian of South Africa
TL;DR: Micropaleontological studies of carbonaceouis chert from the Fig Tree Series of South Africa revealed the presence of spheroidal microfossils, here designated Archaeosphaeroides barbertonensis, interpreted as probably representing the remnants of unicellular alga-like organisms.
Journal ArticleDOI
The alteration of olivine in basaltic and associated lavas
Ian Baker,Stephen E. Haggerty +1 more
TL;DR: Olivines which cool under oxidizing conditions exsolve iron oxides at high temperature, and at low temperatures break down to essentially chloritic materials as discussed by the authors, producing an orientated assemblage of goethite and interstratified phyllosilicates containing a smectite.
Journal ArticleDOI
Evaluating the adsorptive capacity of montmorillonitic and calcareous clays on the removal of several heavy metals in aqueous systems
TL;DR: In this paper, the authors aimed to achieve mineralogical and spectroscopic characterization of Late Cretaceous clays of Aleg formation (Coniacian-Lower Campanian system), Tunisia, for the removal of several toxic metals in aqueous system.
Journal ArticleDOI
X-ray diffraction studies of the thermal behaviour of commercial vermiculites
TL;DR: In this article, the vermiculites were divided into two types: type 1 (Sta. Olalla, Piaui and Goias) and type 2 (Piaui, Goias and Olalla).

The Mineralogy of Glauconite
Graham R. Thompson,John Hower +1 more
TL;DR: In this paper, a good corre- lation has been found between the number of potassium atoms per O(OH)2 in structural formulas calculated from the chemical analyses and the proportion of illite layers as determined by X-ray powder diffraction methods.
