Sandstone diagenesis in a halite deposit, from surface to high-grade diagenesis (Haselgebirge Formation, Eastern Alps)

Abstract The evaporitic Haselgebirge Formation of the Northern Calcareous Alps was deposited in an evolving rift during the Upper Permian. The Jurassic to Cretaceous Alpine orogenesis caused an overprint of ~200 °C. The aim of the study was to investigate the diagenetic evolution of these evaporite-dominated sediments from intact sandstone lenses. Field work, thin section analysis, SEM and XRD were completed by measurements of organic material and age dating. In this paper, we show that all authigenic minerals developed step by step on a prograding path, but under low temperatures of
