Abstract
Fossil shells and paleosol carbonate from ancestral Himalayan river deposits provide a 87 Sr/ 86 Sr record of lowland Himalayan river water during the late Neogene. Reconstructed 87 Sr/ 86 Sr river values increased sharply in the late Miocene, probably marking the beginning of exhumation of high- 87 Sr/ 86 Sr metalimestones, more in the central than in the western Himalayas. These results imply that the marine 87 Sr/ 86 Sr record may not be a proxy for silicate weathering or consumption of atmospheric CO 2 resulting from that weathering.Keywords
