Title: DISCOVERY AND PRELIMINARY STUDY ON PALYNOFOSSILS FROM THE PALEOGENE LIUQU CONGLOMERATES IN SOUTHERN XIZANG(TIBET)
Abstract: This paper reports the first palynological study of interlayers of mudstones and mud-sandstone in the Liuqu Conglomerates.Fifty-two genera were identified in this palynological assesmblage.The assemblage are characterzed by the predominant angiosperm pollen grains(62.77%—83.19%) .The second common group is gymnosperm pollens(11.95%—32.31%) ,and pteridophyte spores are relatively rare(4.80%—10.38%) .Among the angiosperm pollens the most abundant are porate pollens,followed by tricolporate and tricolpate pollens in a moderate percentage.Bisaccate pollens dominate the gymnosperm pollens.The palynological assemblage from the Liuqu Conglomerates suggests a age of the Late Paleogene and a broad-leaved deciduous forest or mixed with conifer-broad-leaved forest,showing a warm-temperate climatic condition.
