    摘要:

    冰川侵蚀山体形成的冰蚀面与冰蚀夷平面,具有鲜明的特征且易于识别,加之冰期具有时间属性与期次性,这对于山体地貌分期研究有着重要的意义。本文在冰蚀地貌研究的基础上,确立了冰蚀地貌与山体隆升之间的耦合关系,并以此建立了华北地区主要山体的地貌分期,划分了渐新世东平冰蚀夷平面(M0)、中新世早期太行冰蚀夷平面(M1)、中新世中期子房冰蚀面(M2)、中新世晚期龙山冰蚀面(M3)与第四纪冰蚀面(M4)等5个基本地貌分期。以此为基础对太行山、燕山、泰山、蒙山、大别山、庐山、嵩山等山体的隆升幅度与隆升速率进行了估算,并与磷灰石裂变径迹测年研究获得的山体隆升过程相对比,两者之间反映出较高的吻合性。研究发现,30 Ma以来,太行山北段(五台山)、燕山、泰山、蒙山、大别山等山体的隆升速率曲线呈“∨”形;庐山、嵩山、太行山南段(云台山)等山体的隆升速率曲线呈“∧”形;太行山中段的隆升过程是“N”形,早期与太行山南段隆升过程一致,后期与太行山北段隆升过程一致。研究认为,以往确认的部分夷平面其本质是冰蚀夷平面,不是风化流水成因;山体瀑布是山体隆升与冰川侵蚀共同作用的结果,与流水无关;岱崮地貌、嶂石岩地貌的成因本质是冰蚀地貌。

    Abstract:

    The ice erosion surface and ice erosion planation surface formed by glacier erosion of mountains have distinct characteristics and are easy to identify. In addition, glacial periods have temporal attributes and periodicity, which is of great significance for the study of mountain landform staging. Based on the study of ice erosion landforms, the coupling relationship has been established between ice erosion landforms and mountain uplift. Based on this, geomorphological stages of the main mountains in north China has been established. It can be divided into Oligocene Dongping Ice Erosion Planum (M0), arly Miocene Taihang Ice Erosion Planum (M1), Mid Miocene Zifang Ice Erosion Surface (M2), Late Miocene Longshan Ice Erosion Surface (M3), and Quaternary Ice Erosion Surface (M4). On this basis, the uplift amplitude and rate of Taihang Mountain, Yanshan Mountain, Mount Taishan Mountain, Mengshan Mountain, Dabie Mountain, Lushan Mountain, Songshan Mountain and other mountains have been estimated. Comparing with the uplift process obtained from apatite fission track dating, the two reflect a high consistency. It is found that since 30 Ma, the uplift rate curves of the northern Taihang Mountains (Mount Wutai), Yanshan Mountains, Mount Taishan Mountains, Mengshan Mountains, Dabie Mountains and other mountains have shown a "∨" shape. The uplift rate curves of mountains, such as Lushan, Songshan, and the southern section of Taihang Mountains (Yuntai Mountain) show a "∧" shape. The uplift process of the middle section of Taihang Mountains is in an "N" shape, which is consistent with the uplift process of the southern section of Taihang Mountains in the early stage and the uplift process of the northern section of Taihang Mountains in the later stage. It is suggested that the previously confirmed partial planation surfaces are essentially ice eroded planation surfaces, not caused by weathered water flow. Mountain waterfalls are the result of the combined action of mountain uplift and glacier erosion, and are not related to flowing water. The essence of the formation of Daigu landform and Zhangshiyan landform is the ice erosion landform
