Abstract

Fossil shells and paleosol carbonate from ancestral Himalayan river deposits provide a 87Sr/86Sr record of lowland Himalayan river water during the late Neogene. Reconstructed 87Sr/86Sr river values increased sharply in the late Miocene, probably marking the beginning of exhumation of high-87Sr/86Sr metalimestones, more in the central than in the western Himalayas. These results imply that the marine 87Sr/86Sr record may not be a proxy for silicate weathering or consumption of atmospheric CO2 resulting from that weathering.
