摘要
The Nanhao Formation is a rock-stratigraphic unit at the bottom of Neopaleozoic transgressive sequence. Recently, some researchers collected Silurian fossils in the second bed of the lectostratotype section, and they thus hold that the lectostratotype section belongs to Silurian instead of Carboniferous, that the Nanhao Formation is not in angular unconformity contact with the underlying strata, and that the Nanhao Formation should be abandoned. The authors point out that the Silurian fossils in the second bed of the lectostratotype section are actually collected from the Silurian strata that underlie the Nanhao Formation, and hence the Nanhao Formation should not be abandoned.
