Abstract: Based on the observations on the mineral and geological markers,palaeobiota,and diversity of spore-pollens,this paper deals with palaeoclimate markers preserved in the strata.Palaeoclimates and their evolutions in various times in Tertiary period are conjectured.This may provide a theoretical basis for the prospect and exploration of petroleum,coal and ironore
