During Triassic times, the Northern Calcareous Alps were situated at the northwestern margin of the Tethys ocean. Succeeding the Permian and Lower Triassic red bed stage, shallow-water carbonates were the main constituents of the Middle and Late Triassic strata, in addition to some mixed carbonate-clastic deposits and basin carbonates. Biostratigraphic data enables exact positioning of the depositional sequences. Despite many good correlations with other Alpine regions as well as with epicontinental Triassic units of central, northwestern and northern Europe, no correlative sequences exist in the Northern Calcareous Alps during late Anisian, late Ladinian, early Carnian and probably Norian times....
