From shallow-water carbonate ramp to hemipelagic deep-marine carbonate deposition: Part 1. General characteristics, microfacies and depositional history of the Middle to Late Anisian Bulog sedimentary succession in the Inner Dinarides (SW Serbia) [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2023
The opening of the Neo‐Tethys started in the Middle Anisian and is recorded in the drowning succession of the shallow‐water Ravni/Steinalm Carbonate Ramp and the subsequent deposition of deep‐marine limestones, e.g., the red nodular limestones of the ...
