Stratigraphy
Formation:Erdaogou
Stratigraphic resolution:member
Stratigraphy comments: Except where otherwise stated, ref. 7624 uses Lower Silurian as equivalent to Llandovery, Middle Silurian as equivalent to Wenlock, and Upper Silurian as equivalent to Ludlow plus Pridoli. Several different working groups have studied this formation and have subdivided it differently. Ref. 7624 seems inclined to accept the subdivision of the Shenyang Institute into a lower, mainly siliciclastic unit that is Pridolian by ref. 7624, and an upper, mainly carbonate unit that is assigned to the Gedinnian by ref. 7624. Shales unconformably overlying this carbonate unit are thought to be Carboniferous (yield Productus and Fusella). An alternative lithologic sequence is given by Liu and Huang (1977), in which the lithologies mentioned are yellow-green siltstone, gray coarse-grained sandstone, and gray calcareous shale with intercalated limestone lenses.
Lithology and environment
Primary lithology: "limestone"
Lithology description: "upper part of the formation, the limestone member...exposed thickness of 36 m"
Environment:marine indet.
Geology comments: Correlation chart indicates BA 4-5 position.
Taphonomy
Collection methods and comments
Reason for describing collection:biostratigraphic analysis
Collection method comments: Collection 25840 is also from the upper part of this formation and has elements in common with this collection, but does not appear to be a subset strictly speaking.
