Stratigraphy
Formation: | Xiushan | Member: | Upper | ||
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. "The age of the Xiushan Formation is still an open question...On the chart we place the lower member in the latest Llandovery and the upper member in the latest Llandovery to early Wenlock." (Formation overlies Rongxi Fm., which is regarded as Telychian.) More recent data puts in in Telychian only, as the overlying Huixingshao is considered Telychian (PJW 2018-04-22). |
