웹Black shales may serve as an important source of metals such as Co, Ni, or As, largely due to anoxic to euxinic conditions in association with high concentrations of sulfur leading to efficient scavenging and transport of metals from seawater into the seafloor sediment. We report on an unusual type of Au mineralization newly discovered in Ediacaran trench-slope black shales … 웹The magnetosusceptibility event and cyclostratigraphy (MSEC) record for the Přı́dolian–Lochkovian (Silurian–Devonian) Global Boundary Stratotype Section and Point (GSSP) (Klonk, Prague Basin, Czech Republic) is described and used to establish a magnetostratigraphyStratotype Section and Point (GSSP) (Klonk, Prague Basin, Czech
