Basis of coordinate: | based on political unit |
Geographic resolution: | local area |
Time
Period: | Devonian | Epoch: | Early/Lower Devonian |
Stage: | Emsian | 10 m.y. bin: | Devonian 2 |
Key time interval: | Early/Lower Emsian | ||
Age range of interval: | 407.60000 - 398.30000 m.y. ago |
Stratigraphy
Formation: | Salairka Horizon | Member: | Middle Salairka Beds | ||
Stratigraphic resolution: | formation | ||||
Stratigraphy comments: Here are the subdivisions of the Telengitian Stage in type locality. Authors correlate stage roughly with Emsian, but note that the Salairka Horizon is said to correlate with the dehiscens Zone, which, according to Harland et al. 1990 is Pragian.
JA: the dehiscens zone is actually early Emsian Telengitian Stage Shanda Horizon Upper Shanda Beds c.partitus/c.patulus Zone Telengitian Stage Shanda Horizon Middle Shanda Beds serotinus Zone Telengitian Stage Shanda Horizon Lower Shanda Beds P.n.sp./inversus Zone Telengitian Stage Belovo Horizon gronbergi Zone Telengitian Stage Salairka Horizon Upper Salairka Beds dehiscens Zone Telengitian Stage Salairka Horizon Middle Salairka Beds dehiscens Zone Telengitian Stage Salairka Horizon Lower Salairka Beds dehiscens Zone |
Lithology and environment
Primary lithology: | "reef rocks" |
Secondary lithology: | "limestone" |
Lithology description: Beds in type sections divided into a number of facies and subfacies: A: "consists mainly of biogenic-clastic limestone." A1: "coral limestones interbedded with siltstones and mudstones containing plant remains" A2: "massive reefal limestones" / "biogenic-clastic limestones, locally with coral bioherms" B: "composed chiefly of mudstones" B1: "interbedded with limestones and richly fossiliferous" B2: "barren" C: "consists of bedded, platy, clayey limestones locally marked by traces of subaqueous slumping" D: "may be equated with a sandy-muddy member with abundant plant remains" | |
Environment: | marine indet. |
Geology comments: Initiation of Telengitian marked by transgression, and termination by regression. Smaller cycles within the stage. |
Taphonomy
Modes of preservation: | body |
Size of fossils: | macrofossils |
Collection methods and comments
Collection excludes: | some macrofossils |
Reason for describing collection: | biostratigraphic analysis |
Taxonomic list comments:Material listed includes fish, plants, conodonts, ostracods, brachiopods, and rugose corals. Bryozoans, trilobites, tabulate corals, and crinoids are also known from these sections, but these have not been studied as completely and are not reported here. |
