(2001): Brachiopod and fusulinid assemblages of Kasimovian (Pennsylvanian) age from the Andara Massif (Picos de Europa, northern Spain).
Crinoid, Bivalve, Brachiopod, Fusulinid, Bryozoanal Calcareous Sandstone Facies (MF9): This facies is 3.77m thick.
According to our findings, the event level coincides with the base of the Bairdia aculeata ostracode Zone in the carbonate-siliciclastic rocks of the Sargian Substage or with the upper boundary of the Eoparafusulina lutugini--Pseudofusulina juresanensis fusulinid Zone in the shallow reef deposits of the Irginian Substage.
The wackestones and packstones are very fossiliferous, and contain abundant brachiopods (Figure 4C), bivalves, some bryozoans, and fusulinid foraminifera (e.g., Triticites).
The lower Lamar yields Yabeina Deprat, a Tethyan Capitanian fusulinid genus.
These facies constitute, a) thick bedded fusulinid rich sandy limestone facies (AMB1), b) bioturbated limy sandstone facies (AMB 2), c) thin to medium bedded diverse bioclastic limestone facies (AMB 3), d) lime mudstone to wackestone facies interbeded with organic rich clays (AMB 4), e) thin to medium bedded sandstone facies (AMB 5).
Based on the integration of the outcrop data, facies information and fusulinid biostratigraphy the dynamic depositional model of the Chhidru Formation is presented.
Thin sections were prepared and classified into six microfacies based on field and petrographic observation as AMB 1: Thick bedded sandy fusulinid packstone microfacies AMB 2: Medium bedded bioturbated sandy wacke-packstone microfacies AMB 3A: Bryozoans rich packtone facies AMB 3B: Diverse bioclastic wackestone facies AMB 4: Mud-wackestone microfacies interbedded with organic rich clays AMB 5: Medium bedded quartz arenite microfacies according to Dunham (1962) for carbonate and Pettijohn et al.
Waagen's lithostratigraphic subdivision was used almost for one century until Kummel and Teichert and associates in 1960's redefined the litho stratigraphy of the Salt Range and Surghar Ranges in terms of modern stratigraphic nomenclature practices as well as piloted a detailed paleontological study of the rich Late Permian and Early Triassic faunas; such as brachiopods, Ammonites, conodonts, bivalves, fusulinids, etc.
