Late Permian (Zechstein) carbonate-facies maps, the Netherlands

摘要

The Late Permian Zechstein carbonates in the Southern Permian Basin were deposited under marine conditions. The carbonates from part of a largely progradational infill, with a gradual northward facies shift. The paleogeography carbonate deposits has been reviewed recently on the base of well data, cores and publications. This has re dated maps of the carbonate units. These maps reflect the increase in knowledge of the paleogeography of result of several decades of subsurface exploration. It is found that deposition of die carbonates was control tors, i.e., rifting during deposition of the basal Zechstein, sea-level fluctuations and basin subsidence. This r all E-W orientated facies distribution in the Zechstein carbonates, and in the gradual northward shift of belts in time.Reefs in the Zl Carbonate Member and off-platform highs and turbidites in the Z2 Carbonate Member identified as potential future exploration targets.
