Geography
Country: | Greenland |
Coordinates: | 74.1° North, 23.0° West (view map) |
Paleocoordinates: | 30.8° South, 48.9° West |
Basis of coordinate: | estimated from map |
Geographic resolution: | outcrop |
Time
Period: | Cambrian | Epoch: | Early/Lower Cambrian |
10 m.y. bin: | Cambrian 2 | ||
Key time interval: | Dyeran | ||
Age range of interval: | 516.00000 - 513.00000 m.y. ago |
Stratigraphy
Formation: | Bastion | ||||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: SPECIFIC COMMENTS: Collection is from the base of the upper (shale) part of the Bastion Formation.
GENERAL COMMENTS: The Kloftelv Formation is overlain by the fossiliferous Bastion and Ella Island foramtions, both of middle Dyerian age (late Early Camrbian, equivalent of the Botomian). The Bastion Formation is 150 m thick at Athe Albert Heim Bjerge locality is mainly galuconite-rich sandstone and siltstone in the lower part and shale with minor carbonate in its upper part. |
Lithology and environment
Primary lithology: | "shale" |
Includes fossils? | Y |
Lithology description: Shale with minor carbonate. | |
Environment: | marine indet. |
Geology comments: The Bastion and Ella Island Formations from part of a thick succession of shallow-marine Proterozoic-Ordovician sediments deposited on the Laurentian shelf. |
Taphonomy
Modes of preservation: | body |
Size of fossils: | macrofossils |
Collection methods and comments
Collection excludes: | some macrofossils |
Collection methods: | bulk,chemical,acetic,sieve,field collection,survey of museum collection |
Reason for describing collection: | taxonomic analysis |
Collection method comments: Rock samples were dissolve in buffered 10 percent acetic acid to retrieve acid-resistent microfossils. The resulting residues were sieved and the heavy mineral fraction separated using sodium polytungstate. All specimens are housed in the Geological Museum in Copenhagen (MGUH) | |
Taxonomic list comments:Exhaustive for Brachiopoda. The residues of the acid-digested samples contain a well-preserved and diverse small shelly fauna including helcionellid molluscs, coelosclerites, lapworthellids, and problematic fossils. Add Gubanov et al. press and Skovsted in press (at the time of April, 2005) for complete fauna - references in current reference. |
