RESEARCH PROGRESS IN METHODOLOGY FOR PALEOELEVATION RECONSTRUCTION OF THE TIBETAN PLATEAU

摘要: 青藏高原隆升对亚洲及全球气候变化有着深刻的影响,因而地质时期青藏高原古高度定量化恢复对于理解高原隆升历史、隆升机制及其环境效应都具有非常重要的意义。通过近十余年的发展,反演高原古高度方法有了很大的发展,这些方法包括气泡法、古植物学、稳定同位素和陆地宇宙核素方法等,这些研究为恢复古高度提供了新的思路和手段。综述并简要介绍了这些方法的基本原理,同时讨论了应用各种方法的局限性,希望能进一步促进我国在高原古高度恢复方面的研究。Abstract: The uplift of the Tibetan Plateau has profound influence on changes of the Asian and global climate. Therefore, the quantitative reconstruction of paleoelevation of the Tibetan Plateau is a key link to understand the history and mechanism and even environmental consequence of the tectonic uplift. Through about ten years' effort, scientists have made great progress in the methodology of paleoelevation reconstruction. These methods include vesicular basalts paleoaltimetry, fossil floras paleoahimetry, stable-isotope paleoaltimetry and terrestrial cosmogenic nuclides paleoahimetry etc. The developments of these methods provide new ideas and tools to reconstruct the paleoelevation. In this paper, we suramarize basic theory of these methods and discuss their limitations in application so as to promote the research on paleoaltimetry of the Tibetan Plateau in China.
