Kede Fm
Type Locality and Naming
It was named by Lin Baoyu and Qiu Hongrong in 1983. The type section is located at the southwest slope, approximately 1 km southeast of Kede Village, Pazhuo District, Dingri County, Xizang Zizhiqu. Xia Daixiang et al. (1997) correlated this formation with the upper part of Pulu Formation and considered this formation name as an invalid name. We retain this formation herein tentatively for further investigation.
