The Lowest Boundary Age of Travertine in Dawanzhangjia Ravine, Huanglong, China

摘要

Objective One of major challenges in paleoenvironmental reconstruction using travertine in the Huanglong area is whether one can accurately determinate the age of travertine through high-precision and high-resolution dating techniques.Previous works of ^(14)C or ESR chronology,however,have shown that the variation of deposition ages of travertine was displayed
