Controlled Drilling Quaternary Pollen Composition and Evolution of Ancient Climate and Environment of Xingtai Purple Mountain West Fault

摘要: 通过对邢台紫山西断裂控制性钻孔中孢粉样品化验分析，依据主要孢粉类型组合和成分含量变化，结合控制性钻孔揭露的地层剖面岩芯的岩性、岩相、层序和热释光测年数据等综合分析，划分出5个孢粉组合带，并根据这5个孢粉组合带孢粉特征，进一步得到邢台地区第四纪以来古气候特征及其变化过程。

Abstract: In this paper, we analyze the assay results of pollen samples in controlled drilling in Xingtai Purple Mountain west fault according to thir main pollen type combinations and ingredients change. Combining with comprehensive analysis of the lithology, facies, sequence and TL dating data of of the stratigraphic section cores uncovered through the controlled borehole, the pollen samples are divide into five pollen combinations. According to the pollen features of the five pollen combinations, we obtain the paleoclimate characteristic and its changing process in Xingtai area since the Quaternary.
