| 摘 要： | 通过解读大气降水的氧同位素组成和现代温度与海拔之间的关系,可以揭示山脉水系及湖相碳酸盐沉积中的稳定氧同位素与海拔高度存在一定的经验关系。氧同位素古高程计对理解山脉演化提供了关键的高度信息。这种方法可用于定量估算山脉古海拔,为反演山脉隆升历史提供了新的研究思路。总结了前人对青藏高原隆升高度的估计,并对比其他方法与此方法的差异,发现此方法在具体应用方面还存在一定的局限性。由于受采样点选取、曲线拟合模式等多方面因素的制约,在应用过程中应给予充分考虑。

| Abstract: | An empirical relationship was found between elevation and oxygen isotope composition of lacustrine carbonate and surface water by analysing the relationships between modern meteoric water,temperature and altimetry.Oxygen isotope paleoaltimetry provides surface elevation information that is crucial to deciphering the topographic evolution of mountain belts.This method can be used to quantitatively estimate the elevation of the mountains and thus it provides a new way to reconstruct the history of mountain up... |
