TL;DR: In this paper, a method was developed to separate nano-particles of amorphous material from Syncrude fine tailings using elemental analysis, X-ray powder diffraction, XPS, SEM, infrared spectroscopy, solid-state NMR, density, and surface area measurements.

TL;DR: A selection of these techniques, of proven value in specific studies, has been brought together in this chapter in the hope that they will contribute to carbonate studies in general.
Abstract: Summary The increasing emphasis on detailed study of the petrology of carbonate rocks has led to the adoption of a multitude of techniques that are described in a series of widely scattered publications. A selection of these techniques, of proven value in specific studies, has been brought together in this chapter in the hope that they will contribute to carbonate studies in general. In many cases, refinements and an increase in reliability of a particular technique will rest on a simultaneous use of associated methods and modifications to suit specific cases. The interpretation of the analytical results must be based on sound genetic concepts, which in some instances also require new approaches as discussed in other chapters in this book.

TL;DR: In this article, the authors investigated the composition, micromorphology and mineralogy of iron-manganese concretions from three reference soil series of the Indo-Gangetic plain of Punjab.

TL;DR: Fibrillar pseudoboehmite and euhedral lath-like boehmite aqueous sols were prepared from the reaction of aluminium secondary butoxide and acetic acid in order to have a solid content of 70g/1 of AlOOH as discussed by the authors.

TL;DR: In this article, it has been found that the former mineral assemblage resulted from the alteration process is associated with the uranium mineralization and follow progressive reaction series, indicating palaeoenvironmental (cycles of tropical humid to semi-arid/arid) changes prevailed during maturation.
Abstract: Clays associated with the Precambrian unconformity-related (sensu lato) uranium mineralization that occur along fractures of Rohini carbonate, Bandai sandstone and clay-organic rich black carbonaceous Gorakalan shale of the Sonrai Formation from Bijawar Group is significant. Nature and structural complexity of these clays have been studied to understand depositional mechanism and palaeoenvironmental conditions responsible for the restricted enrichment of uranium in the Sonrai basin. Clays ( chlorite > illite > smectite mineral assemblages, whereas, Solda Formation contains kaolinite > illite > chlorite clays. It has been found that the former mineral assemblage resulted from the alteration process is associated with the uranium mineralization and follow progressive reaction series, indicating palaeoenvironmental (cycles of tropical humid to semi-arid/arid) changes prevailed during maturation of the Sonrai basin. The hydrothermal activity possibly associated with Kurrat volcanics is accountable for the clay mineral alterations.

...The mineral phases were identified by comparing these spectra with standard X-ray diffraction data of the clay minerals available in the JCPDS/IDD Files (Brown, 1961; Wilson, 1987; Tucker, 1988; Tan, 2005)....
