Brief Communication: New evidence further constraining Tibetan ice core chronologies to the Holocene

There is considerable controversy regarding the age ranges of Tibetan ice cores. The Guliya ice core was reported to reach as far back as ~ 760 ka (thousand years), whereas chronologies of all other Tibetan cores cover at most the Holocene. Here we present ages for two new ice cores reaching bedrock...
