Paibi

Paibi (Chinese: 排碧; pinyin: Páibì), a village in Paibi Township (排碧乡), Huayuan County, Xiangxi Tujia and Miao Autonomous Prefecture Hunan, China,^[1] is the location of the Global Boundary Stratotype Section and Point (GSSP) which marks the boundary between the third and Furongian epochs of the Cambrian Period on the geologic time scale. Paibi was selected over the Kyrshabakty River section, Malyi Karatau, Kazakhstan, and the GSSP was ratified by the International Union of Geological Sciences in late 2003. It established the first formally agreed upon subdivision of the Cambrian. The village gives its name to the Paibian Age in the Cambrian Period.

The Paibi section occurs within the

deposited in the outer part of the Jiangnan Slope Belt, and extends from the middle Cambrian through the Lower Ordovician. It satisfies all the geological and biostratigraphic requirements for a GSSP, is readily accessible, and includes chemostratigraphic, palaeogeographic, facies-relationship, and sequence-stratigraphic
