TL;DR: Results demonstrate that Pb, Zn, Cu, Sb and Hg can be inferred to be tracers of anthropic pollution, whereas Mn, Ni, Co, Cr, V and Cd were interpreted to be mainly inherited from parent materials.

TL;DR: In this paper, the authors examined surface samples of shales ranging in age from Pleistocene to Eocene obtained from five Gulf Coast oil wells to determine the nature and extent of burial diagenesis in pelitic sediments.
Abstract: Subsurface samples of shales ranging in age from Pleistocene to Eocene obtained from five Gulf Coast oil wells were examined mineralogically and chemically to determine the nature and extent of burial diagenesis in pelitic sediments. Illite/montmorillonite dominates the mineralogy and undergoes a monotonic decrease in expandability from about 80 to a limit of 20 per cent montmorillonite layers with increasing depth. The interstratification changes from random to ordered at about 35 per cent expanded layers. Discrete illite and kaolinite phases are ubiquitous and judged detrital. The discrete illite (mica) content of the whole rock decreases with depth, while the kaolinite shows no systematic variation. Chlorite occurs in appreciable amounts in only one well and there only in samples from the shallow water facies. This chlorite is also considered detrital.

TL;DR: This mineral showed the same high sorption capacity values when used in the purification of metal electroplating waste waters, appearing, therefore, as most suitable to perform metal waste water purification processes.

TL;DR: The major and trace element chemical composition of shales and sandstones from the Iberian Range (Spain) has been investigated to determine the provenance and tectonic setting of these rocks, as well as to appraise the influence of the weathering, hydraulic sorting and recycling processes upon source rock signature as mentioned in this paper.

TL;DR: In this paper, the interpretation and significance of some of the clay mineral components of recent sediments and soil materials are discussed in detail and factors involved in analyzing these materials quantitatively are considered and a general procedure outlined.
Abstract: The clay mineral components of Recent sediments and soil materials exhibit structural attributes unlike those of many so-called standard clay materials. The interpretation and significance of some of these is discussed in detail. Factors involved in analyzing these materials quantitatively are considered and a general procedure outlined.
