| 摘 要： | 简要介绍了盆地沉积物示踪山脉隆升剥蚀的几种方法并给以实例分析。与造山 隆升过程相伴生的沉积盆地记录了造山带隆升的许多宝贵信息，利用盆地沉积物反演原区背景常局限于盆地沉积物碎屑组分、副（重）矿物组合及元素地球化学特征的变化，近年国外已开始利用盆地沉积物中颗粒错石Ｕ－Ｐｂ年龄谱、Ｎｄ同位素组成、矿物（如黑云母、磷灰石等）热年代学方法示踪盆地沉积物物源性质及物源贡献比例，山脉构造热事件及山脉升剥蚀速率等

| Abstract: | Several methods using basin sediment to constrain mountain uplift erosion are introduced.Besides detrital composition,assemblage of accessory mineral and element geochemistary of basin sediments can trace the tectonic environment of the sediment sources,the geochronological and isotopic geochemistrial studies of basin sediments,including U Pb dating on single detrital zircon,isotopic compositions and thermochronology of the minerals,can not only constrain the type and characteristics of the sediment sources,but also quantify exhumation rate,the ratio and relative amounts of the different end members. |
