Mid‐MIS3 climate inferred from reconstructing the Dalijia Shan ice cap, north‐eastern Tibetan Plateau
ABSTRACT The local last glacial maximum (LGM L ) on Dalijia Shan occurred during mid‐marine isotope stage 3 (MIS3), which is consistent with some Tibetan Plateau records, but asynchronous with the MIS2 global Last Glacial Maximum (LGM G ). Paleoclimatic reconstructions are key to advancing understan...

ABSTRACT The local last glacial maximum (LGM L ) on Dalijia Shan occurred during mid‐marine isotope stage 3 (MIS3), which is consistent with some Tibetan Plateau records, but asynchronous with the MIS2 global Last Glacial Maximum (LGM G ). Paleoclimatic reconstructions are key to advancing understanding such spatial and temporal patterns of paleoglaciation. Using multiple methods we reconstructed mid‐MIS3 equilibrium‐line altitude (ELA) on Dalijia Shan and inferred temperature depressions. Geomorphic ELA reconstructions combined with empirical data on current ELA temperature and precipitation yield a mid‐MIS3 ELA of 4000 ± 78 m a.s.l.
