Stratigraphy
Geological group:"Pailungchiang"
Stratigraphic resolution:group
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 does not accept this as Pailungchiang s.s. Age span of "Pailungchiang Group" in correlation chart is Upper Llandovery to Pridoli; I infer that the middle and upper parts would be post-Llandovery.
Lithology and environment
Primary lithology: phyllite
Secondary lithology: argillaceous "limestone"
Lithology description: "...thickness of about 2901 m. The beds are metamorphosed. The consist of phyllite, quartzitic sandstone, and interbedded argillaceous limestone in the middle and upper parts. The Bureau reports a shelly fauna in their section from the middle and upper parts..."
Environment:marine indet.
Geology comments: Correlation chart indicates BA3 based on shelly fauna.
