摘要
By correlated paleoclimate indicators,the paleoclimate evolution during the deposition of Lower Paleogene sediments from Core SB-01 in Sanshui Basin can be reconstructed through the analysis of the compositions of the major elements and the element correlated with organic matters and their paleoclimatic implications using the method of factor analysis,for further understanding of Paleogene paleoclimate of the basin.The main factors influencing the compositions of the major elements and the element correlated with organic matters are precipitation and temperature.Precipitation plays relatively more important role.Based on the change of the factors,the paleoclimate process of the Early Paleogene in Sanshui Basin can be obtained: Stage I(89.0 73.0 m) with drier and colder condition;Stage II(73.0-52.5 m) with warm and moisture condition;Stage III(52.5-22.5 m) a rapid change of climatic condition,alternation between hot-humid and cool-dry;Stage IV(22.5-0 m) with prevailing warm and moisture condition.
