Major lithostratigraphic units of northwest Europe with the ICS's geologic timescale of the Triassic.[1]

Gogolin Formation - Triassic geologic formation, hitherto named the Gogolin Beds,[2][3] is the lowermost lithostratigraphical unit of the Lower Muschelkalk in the Silesian-Cracow Upland (S Poland, Central Europe), underlain by the Upper Buntsandstein (Lower Triassic) carbonates and overlain by the Górażdże Formation (Middle Triassic) carbonates.[4][5]

Name

Historical name coming from Gogolin, a small town in south Poland, where the Gogolin Formation was described for the first time, and where the main stratotypes have been exposed (see section Stratotypes).[4]

Age

The Late Olenekian or Early Aegean (Anisian) to Pelsonian (Anisian),.[6][7]

Rocks

The formation is built of various carbonates which were deposited on a carbonate ramp.[4][8]

The lowermost part of the Gogolin Formation - Gogolin, S Poland

Subdivision

This Formation has recently been divided into four members, six beds, and two horizons:[4][5]

  1. Zakrzów Crinoidal Limestone Member, which includes: a) Krapkowice Pelitic Limestone Bed - thin-bedded, wavy bedded and marly micritic limestones, b) Dąbrówka Bioclastic Limestone Bed - thick- to medium-bedded, cross-bedded crinoidal limestones, c) Podbór Bioclastic Limestone Bed - thin- to medium-bedded, graded, horizontally and cross-bedded bioclastic limestones and wavy-bedded micritic limestones;
  2. The Skała Marl Member - marls interbedded with micritic and bioclastic limestones; the lowermost part of this member is locally built of broken-up limestone beds and lumps which are covered by an intraformational conglomerate with small intraclasts - they are divided as Kocina Intraformational Conglomerate Bed;
  3. The Emilówka Cellular Limestone Member, which includes: a) Karłubiec Bioclastic Limestone Bed - massive, cross-bedded, thin- to medium-bedded bioclastic and micritic limestones, b) Otmęt Marly Limestone Bed - strongly porous, thin-bedded marly limestones that are, in fact, dedolomitized dolomites;
  4. Odrowąż marly limestone horizon - marls, thin- to medium-bedded, graded, cross-bedded and horizontally bedded bioclastic limestones and thin layers of platy and wavy bedded micritic limestones;
  5. Malnia limestone horizon - thin- to medium-bedded, graded, horizontally and cross-bedded bioclastic limestones, thin-bedded, platy and wavy-bedded micritic limestones;
  6. Ligota Hill Wavy-Bedded Limestone Member - wavy-bedded and crumpled micritic limestones intercalated with medium- to thin-bedded, graded,cross- and horizontally bedded, bioclastic limestones.

Stratotypes

Stratotypes are located at Gogolin and its vicinity, Błotnica Strzelecka and Ligota Dolna (southern Poland).[4][5]
