摘要:
通过对福建漳浦前湖湾QHP剖面和钻孔QHZ2沉积物磁学取样及其实验分析,得到各种磁学参数及多个磁参数的比值随样品号(深度)的变化曲线.结合该剖面和钻孔的粒度特征、孢粉分析和14C测年,结果表明,QHP剖面和钻孔QHZ2沉积物中磁参数及其比值的变化能与其古气候变化很好地相对应,特别是在7号样、13号样、22号样的气候转折点上,沉积物中环境磁参数及其比值出现比较明显的变化.这说明沉积物中磁参数及其比值能较好地记录沉积物沉积时的古气侯,也可用来认识古气侯突变的界线.前湖湾QHP剖面和钻孔QHZ2是晚更新世以来形成的,至少经历了2个暖湿期和2个干冷期,而每一个期内又存在着小的暖湿期和冷干期的交替.
Abstract:
Deposit magnetism sampling and their experiment analysis of the QHP section and the QHZ core 2 of Qianhu bay in Fujian Zhangpu were sdudied.Combined with the size characterristic,sporopollen analysis and 14Cof the section and core,the changing curves of the ratio between the various magnetic parameters and several magnetism parameters with the sample number(depth) were obtained.The result showed that magnetism parameter and their ratio of the QHP section and the QHZ core 2 can respond to their paleoclimate,especially on the climate turning point NO.7,NO.13,NO.22,the environmental magnetism parameter and their ratio appeared obvious change comparatively.These explained that the magnetism parameter and their ratio of the deposit can respond to the paleoclimate of the QHP section and the QHZ core 2 when deposit was depositing,also these can be used to understand the demarcation line of the paleoenvironment changing.The QHP section and the QHZ core 2 of Qianhu bay formed since epipleistocene,which had experienced 2 warm wet period and 2 dry cold period at least and in each period existenced turns between the small warm wet and cold dry period.
