Abstract

P254 Hydrocarbon Generation and Hydrochemical Basin Zonation from Dolomite Cement in Cambrian Sandstones S. Sliaupa* (Institute of Geology and Geography) N. Molenaar (Danish Technical University) & J. Cyziene (Geological Survey of Lithuania) SUMMARY The conditions and timing of carbonate cementation in Cambrian sandstones in the Baltic Basin were constrained by stable oxygen and carbon isotope and chemical data in combination with optical and cathodoluminescence petrographic studies. Studied samples represent a range in present burial depth 340-2150 m. The carbonate cement is dominantly ferroan dolomite that occurs as dispersed patches of poikilotopic crystals. Temperatures of dolomite precipitation based on  18O values
