| Structure and formation conditions of Frasnian section, northwest Pay-Khoy | |
| The Frasnian of the northern part of the Pay-Khoy carbonate parautochton is represented by Pyrkov Formation. The formation disconformally overlays Lower and probably Middle Devonian, and corresponds to beginning of the Late Devonian – Tournaisian cycle of sedimentation. The Pyrkov Formation is composed of the six facial types, which correspond to wide spectrum of environment – from extremely shallow-water up to deep water. The stratigraphical sequence of the facial types allows us reconstructing the appearance of the isolated carbonate platform (shoal) in the late Frasnian. Local microbial and algal bioherms are characteristic for the late Frasnian. The bioherms were partly eroded during the Frasnian/Famennian regression.
Keywords: stratigraphy, facies, Frasnian, Pyrkov Formation, Pay-Khoy. |
