Preliminary studies of the Pliocene climate and elevation of Zhangcun, Shanxi, China.

Abstract

Abstract:

The Pliocene climate and elevation of Zhangcun basin are estimated using ODA method, based on the data of both plant fossil and pollen assemblages. The results show that (1) the data of the palaeoclimate parameters obtained from ODA analyses of both megafossil and three sets of pollen assemblages mostly fall into the range of modern warm temperate and northern subtropical zones; that (2) the palaeoelevation of Zhangcun estimated by the assemblage of plant megafossils found in situ ranges from 4001000 m a.s.l. and obviously lower than today (1043 m a.s.l.). The findings might indicate the uplift of Zhangcun basin on the east edge of the Loess Plateau after the Pliocene, and support the former view that the elevation of southeastern Shanxi had risen slowly since the Pleistocene.

Key words: palaeoclimate, palaeoelevation, Pliocene, Zhangcun, Shanxi, , China
