OSL and pollen concentrate ~(14)C dating of dammed lake sediments at Maoxian, east Tibet, and implications for two historical earthquakes in AD 638 and 952

【摘要】:正Formation of dammed lakes provides exceptionally important information of continental geological processes,responding to tectonic and climatic influences.Establishing accurate geochronological frameworks within lake strata is challenging because the stratigraphy is often bereft of biostratigraphy and directly dateable material.Optically Stimulated Luminescence(OSL)and AMS ~(14)C dating of pollen concentrates are well-established tools for dating lake sediments.
