地质晚近时期山脉地区隆升及剥露作用研究

对地质晚近时期，特别是新生代以来山脉隆升剥蚀历程的研究，历来受到人们的十分关注。文中介绍了几种有关研究方法的一些新进展：（１）利用宇宙核素估算山体表面剥蚀速率和表面隆升速率；（２）利用磷灰石裂变径迹研究山脉地区岩石的隆升剥露；（３）利用地貌有关参数判断因侵蚀作用引起的均衡抬升和构造作用引起的构造抬升在山脉地区高峰形成中的贡献。

SOME PROGRESSES OF RESEARCH METHODS ON THE UPLIFT AND EXHUMATION OF CENOZOIC

The uplift and exhumation in the mountains during Cenozoic have been attracted close attention of many geologists because most of the mountains in the world showed intensive uplifting and influenced the variation of climate in Cenozoic. There have occurred some new methods in recent years which are used to study the uplift and exhumation history of the mountains during Cenozoic. Some new progresses of the research methods are summarized from the following three aspects: (1) to determine the surface erosion rates and surface uplifting rates of the mountains by measuring in situ produced cosmogenic nuclide; (2) to determine the uplift and exhumation history of the rocks and the surface of the mountains by studying the apatite fission track; (3) to estimate the relative contributions of isostatic uplift and tectonic uplift in the intensive dissected mountains by morphologic parameters.
