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. "Ni Yu-nan and others (in press) described this unit. When they measured the type section of the Jenhochiao Formation at Hunshuitang...they reported [it]...[The] fauna indicates a Ludlow to Pridoli age." The unit is faulted off at the base. A minimum thickness is about 50 m." |
