Stratigraphy
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. "The rocks have been assigned to the Upper Silurian, but these two tabulates suggest little more than a Silurian age. The type Bateaobao Formation has a lot of red limestone that is completely missing from the Abagaqi County occurrences, and the type lacks both slate and sandstone, so that we feel that quotation marks are necessary for this unit." Favosites and Mesofavosites reported from upper part of section.
