Lacustrine Paper Shales in the Permocarboniferous Saar-Nahe Basin (West Germany) — Depositional Enviraphy and geochemistry..The lakes formed mostly on flood plains associated with fluvial environments. They were exposed to a tropical climate. Thus, the bedding of the lacustrine shales shows an even lamination from layers of light silt to dark clay. The graded silts are correlated with the suspensi

The Pollution of the River Rhine with Heavy Metalsckground pollution counts are around 20% for Pb and Zn, > 20% for Hg and Cd, 40% for Cu, 50% for Cr, and 60% for Ni. As a third source diffuse pollution (rain, surface erosion, etc) plays a role especially with Zn, Cd, Pb. The analytical procedures for evaluating metal concentrations are in some cas

Sedimentological and Petrophysical Aspects of Primary Petroleum Migration Pathwaysh reference to field examples where hydrocarbon expulsion has occurred..It seems likely that the factors determining the dimensions of the three migration pathways — organic, pore and fracture network — have to be quantified in order to evaluate primary petroleum migration mechanism. The respective key factors are:
