Abstract:

Late Pleistocene peat deposits are found in the two drilling cores located to the east and west of Shenyang City separately.The peat from the eastern drilling core was formed in the later Yumuya inter-galacial period and peat from the western core was formed after the Yumuya inter-galacial period. Pollen plant analyses of these two peat deposits show that the peat from the drilling core in the east contain mostly of pollen of deciduous broad-leaf plants indicative of warm and humid climate and those from the drilling core in the west contains pollen of angiosperm and minor needle and broad leaf plants in mountains rerpesentive of temperate and try climate. Quantative paleo-climate analysis suggests that the climate in the later Yumuya inter-galacial period was almost same as the present climate in Shenyang, but the climate after the Yumuya inter-galacial period was a little cooler than today in Shenyang.
