通过对六盘山地区山麓剥蚀面上的红层和陇东盆地的红黏土剖面古地磁测年及地貌地层学研究,发现红层或红黏土均形成于约8.1 MaBP,指示了晚白垩世以来形成的夷平面在此时被断裂错开,发育终止,六盘山开始隆升;在约5.2 MaBP时再次小规模隆升,堆积相应的细砾沉积,并随后剥蚀形成山麓剥蚀面;到约3.8 MaBP,六盘山大规模加速隆起,河流急剧下切,河湖相沉积结束,典型风成红黏土沉积出现.六盘山的隆起过程可较好地与青藏高原及周边山地的隆起过程相对比,它应是青藏高原隆升的响应.
Based on the paleomagnetic dating and geostratigraphy of the red beds on the eroded surface of the foot of the Liupanshan Mountains and the red clay in Longdong Basin, it was found that the red beds or red clay were formed at about 8.1 Ma BP, indicating the formation since the Late Cretaceous At this time, the rupture of the razor plateau was discontinued and the Liupanshan began to uplift. At about 5.2 Ma BP, small-scale uplifting and deposition of the corresponding fine gravel deposits followed by denudation to the piedmont erosion surface. At about 3.8 Ma BP, Liupanshan large-scale accelerated uplift, the river drastically cut, the river lacusse facies deposition, the typical wind into the red clay deposition.Liupanshan uplift process can be better with the Qinghai-Tibet Plateau and the surrounding mountain uplift process, it should be the Qinghai-Tibet Response of plateau uplift.
