New knowledge of the age of the beds with small shelly fossils in the Nanking Hills
Zhang Sengui(Nanjing Inst. of Geol. & Palaeont.,Academia Sinica, Nanjing, 210008)
Judged from the characteristics and the sedimentary environments of the faunas, the beds yielding small shelly fossils of the Mufushan Formation in the Lunshan area of Jurong are identical in the stratigraphic sequence with the beds with small shelly fossils and trilobites in the Mufushan area of Nanjing. They are equivalent to Paokannia Zone of the Lower Cambrian Tsanglangpu Stage. This small shelly assemblage is the latest one of the Early Cambrian in the whole China. The Lunshan area was located on the margin of the carbonate platform during the Late Sinian-Early Cambrian and was devoid of sediments from the early Early Cambrian to the middle Tsanglangpu period.
