The Demerara Plateau is a marginal plateau which forms a bathymetric relief on the sea floor. Here, contourite deposits have been studied in detail, following the recent discovery of contourite sequences likely related to the bottom currents and linked both to contour current and peculiar sea-fl...detailed
Although the Middle Eocene sediments at the Nile Valley, Egypt have been extensively studied, the origin of glauconites in these sediments is still questionable. In this paper, the glauconites that occur in the Qarara Formation were subjected to petrographical and mineralogical studies to assess...detailed
The purpose of the study was to investigate glauconite weathering in regolith profile developed on Santonian marls in Zabierzów (South Poland) most likely during Paleogene. Because of the high carbonates content the studied regolith appears to constitute a unique case where glauconite underwent...detailed
The aim of the present study was to investigate the process of glauconite weathering in an alkaline soil under temperate climatic conditions. Calcaric Cambisol developed on Miocene sand in eastern Poland, and the sand containing parent glauconite, were sampled and analyzed using optical microsco...detailed
