The Upper Triassic red beds (Moesian Group) in the Golo-bârdo unit are subdivided into three formations. The basal Slavey Formation is situated over the Upper Triassic dolomitic Rusinovdel Formation, and consists of variegated marls, dolomites, and oolithic, nodular or biodetritic limestones often containing foraminifers, ostracods, algae and coprolites. The foraminiferal assemblage includes Angulodiscus friedli, Nodosaria ordinata and Semiinvoluta clari, and indicates a Norian age. The following Komštica Formation (red shales, siltstones and sandstones) and Vetruška Formation (variegated conglomerates built up of carbonate pebbles) are situated in superposition and with lateral interfingering. The section of the Moesian Group in the Golo-bârdo unit is covered after wash-out and with a slight unconformity by the Middle Jurassic Polaten Formation. The pebbles in the Vetruška Formation come mostly from the Upper Triassic Rusinovdel and Trân Formations, and the Anisian-Ladinian radomir Formation. The pebbles from the Radomir Formation yielded conodonts which prove the conodont zones Pridaella cornuta R. Z., Pridella excentrica I. Z. and Pridaella bakalovi R. Z. The pebble content of the Vetruška Formation hints to the Ljubaš unit (situated at northwest of the Golo-bârdo unit) as the possible source area of the pebbles as far as the Lower Triassic and Lower Anisian formations in this unit are covered directly by Lower and Middle Jurassic formations thus indicating a deep Late Triassic erosion and denudation. This evidence disproves the idea about a complete alochthoneity of the Golo-bârdo unit.

Four formal lithostratigraphic units are introduced for the first time in the national stratigraphic nomenclature in accordance with the National Stratigraphic Code and the International Stratigraphic Guide. The Upper Triassic Kobile Formation is situated at the top of the Triassic section (over the red beds of the Norian Komshtitsa Formation). It consists of phosphate- and sulphate-bearing yellowish sandstone and siltstone interbedded with grey limestone and dolomitic limestone. Occasionally, they contain echinids, gastropods, crinoid ossicles, algae and foraminifers. The Metohiya Fonnation (basal conglomerate built up of quartz and Iydite pebbles; quartz sandstone; loose yellowish sandstones and occasional limestone interbeds) covers the Upper Triassic with unconfonnable depositional contact. The age is considered as Middle Jurassic (eventually beginning in uppermost Lower Jurassic) on the basis of regional correlations. The other two newly introduced Jurassic formations belong to the Treklyano Group and are of Middle - Late? Jurassic age. The Momchil Formation is built up of shales and siltstones interbedded with limestones. The Sredorek Formation consists of limestones and marls with shaly interbeds and olistostrome built up of Triassic limestones and siltstones. Lateral correlations with the deep marine sequence (shales and radiolarites) of the Dobridol and Rayantsi Formation make possible the reconstruction of a Jurassic narrow and deep submarine canyon within the Peri-Tethyan shallow sea.

The facies development of the Spanish Triassic corresponds to the typical three‐fold subdivision of the Germanic Facies: Buntsandstein, Muschelkalk and Keuper. Two intervals interpreted as epeiric carbonate platforms: lower Muschelkalk (Anisian) and upper Muschelkalk (Ladinian) are recognized during the Middle Triassic of northeastern Spain. These carbonate intervals are separated by one siliciclastic/evaporitic interval interpreted as sabbkha and saline deposits: middle Muschelkalk facies (Lower Ladinian). In northeastern Spain (Catalonian Coastal Ranges), two Middle Triassic sections comprising lower Muschelkalk facies have yielded the following conodont taxa: Paragondolella bulgarica, P. hanbulogi, P. bifurcata, Neogondolella constricta, N. cornuta, N. excentrica and N. basisymmetrica. The conodont sequence allows recognition of the P. bulgarica and N. constricta zones. These results indicate a middle–upper Pelsonian to upper Illyrian age (middle–upper Anisian), and represent the first conodont‐chronostratigraphic approximation for the lower Muschelkalk facies of the western part of the Sephardic Province of the Triassic Tethys Realm.
