临夏盆地晚新生代沉积特征与青藏高原隆升
摘要
临夏盆地是青藏高原东北边缘的一个新生代断陷盆地
盆地中的新生代沉积蕴含了丰富的环境演变等信息
并具鲜明的特征
其演化及宏观地貌结构特征的形成具有深刻的构造、气候演变及区域性特征背景
其中构造背景 -青藏高原的隆升对其的影响尤为突出
其中发生了 3.2 Ma B.P.、5 .3.Ma B.P.、2 .4 Ma B.P.和 1.6 Ma B.P.的几次强烈的构造运动对于其现代地貌格局与特征的形成具有重要意义 .一系列重大地质事件
如黄河于 1.6 Ma B.P.在盆地中出现、河流阶地系列的形成和风成黄土的沉积等青藏高原的阶段性整体隆升密切相关 .
Abstract
Linxian basin
a tectonic original faulted cenozoic basin
lies on the northeastern margine of Tibetan plateau.The cenozoic deposit in this basin stores plentiful information indicating paleoenvironmental changes.The geomorphologic development of this basin was influenced greatly by the uplifts of Tibetan plateau and paleoclimatic changes.Several important geologic events
for example
the appearance of Huanghe river at about 1.6MaB.P.
the formation of terrace seres and deposit of eolian loess
are closely related to the upheave of whole Tibetan plateau.
