Stratigraphy
Stratigraphic resolution:group of beds
Stratigraphy comments: Lower Spathian, equivalent to Tirolites cassianus ammonoid zone. Triassospathodus hungaricus fauna.
Lithology and environment
Primary lithology:shelly/skeletal lithified packstone
Secondary lithology: lithified lime mudstone
Environment:deep subtidal ramp
Geology comments: Sedimentation of the dominantly fine-grained microfacies type B can be interpreted as slow deposition in a deeper marine environment below the fair-weather wave base, which corresponds to the distal part of a ramp. Nevertheless, the interlayering with limestone of microfacies type A suggests that slow deposition of fine-grained sediments (microfacies type B) was
periodically interrupted by the deposition of coarse skeletal detritus during high-energy events (microfacies type A).
