Stratigraphy
Formation:Pailungchiang
Stratigraphic resolution:formation
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. Ref. 7624 refers to Pailungchiang as formation, whereas previous working groups called it a group. Collection is from upper subgroup (subformation). Sichuan Working Group dated this part of formation as Middle-Upper Silurian; ref. 7624 assigns to Ludlow, but that call is based on material from different locality.
Lithology and environment
Primary lithology: sandy slate
Secondary lithology: "limestone"
Lithology description: "In the upper subgroup there is much phyllite and sandy slate, with some limestone, chert, and volcanogenic beds in a few restricted areas."
Environment:marine indet.
Taphonomy
Collection methods and comments
Reason for describing collection:biostratigraphic analysis
Collection method comments: Material studied by the Working Group of the Regional Stratigraphic Chart of Sichuan (1974).
