THE observed trend of increasing oceanic 87Sr/86Sr ratios during the late Cenozoic led Raymo et al.1 to propose that chemical weathering rates increased at this time as a result of enhanced weatherability of silicate rocks. They suggested that this was due in turn to continential uplift, primarily in the Himalayas and the Andes. Because weathering involves the reaction of silicates with atmospheric carbon dioxide, considerations of changes in weathering rates must take into account the need to… Expand

Global Chemical Erosion during the Cenozoic: Weatherability Balances the Budgets
The question addressed here is whether global chemical weathering and erosion rates have increased over Cenozoic time in response to uplift of the Himalayas.1–2 Chemical weathering of the continents… Expand
The Cenozoic evolution of the strontium and carbon cycles: relative importance of continental erosion and mantle exchanges
The past variations of the seawater 87Sr86Sr isotopic ratio are related to changes in the relative contribution of the mantle Sr input to the ocean and the Sr supply from continental weathering.… Expand
Balancing the Cenozoic carbon and alkalinity cycles: Constraints from isotopic records
A simple model of the carbon, alkalinity and strontium cycles is built up and used to interpret the carbon and strontium isotopic evolution of seawater over the Cenozoic as recorded in marine… Expand
The Himalayas, organic carbon burial, and climate in the Miocene
Cooling ages of rock in the Himalayas imply that rapid exhumation between the Main Central thrust system and the South Tibetan detachment system occurred between 21 and 17 Ma. The generation of… Expand
Neogene continental denudation and the beryllium conundrum
TLDR
A beryllium cycle model is presented whose results show that variations in the 9Be weathering flux are counterbalanced by near-coastal scavenging while the cosmogenic 10Be flux from the upper atmosphere stays constant, and predicted seawater 10Be/9Be ratios remain nearly constant even when global denudation and Be weathering rates increase by three orders of magnitude.

Geochemical consequences of increased Late Cenozoic weathering rates and the global CO2 balance since 100 Ma
Large imbalances in the relative net CO2 flux over the last 100 m.y. are obtained from independently derived estimates of CO2 uptake by weathering and organic carbon burial and of CO2 outgassing… Expand
Synchronous changes in seawater strontium isotope composition and global climate
THE 87Sr/86Sr ratio of sea water has increased gradually over the past 40 Myr, suggesting a concomitant increase in global chemical weathering rates1–6. Recently, Dia et al.7 analysed a 250-kyr… Expand
Modulation of Late Cretaceous and Cenozoic climate by variable drawdown of atmospheric pCO 2 from weathering of basaltic provinces on continents drifting through the equatorial humid belt
Abstract. The small reservoir of carbon dioxide in the atmosphere (pCO2) that modulates climate through the greenhouse effect reflects a delicate balance between large fluxes of sources and sinks.… Expand
WAS THE HIMALAYAN OROGEN A CLIMATICALLY SIGNIFICANT COUPLED SOURCE AND SINK FOR ATMOSPHERIC CO2 DURING THE CENOZOIC
The hypothesis that the Himalayan orogen was a climatically significant coupled source and sink for atmospheric CO2 during the Cenozoic is evaluated in light of the timing, duration and CO2 fluxes… Expand

In a steady-state ocean, input fluxes of dissolved salts to the sea must be balanced in mass and isotopic value by output fluxes. For the elements strontium, calcium, and carbon, rivers provide the… Expand

TLDR
A history of atmospheric carbon dioxide and climate during Phanerozoic time, consistent with the strontium isotopic data, is reconstructed and is shown to be compatible with paleoclimatic indicators, such as the timing of glaciation and the estimates of Cretaceous paleotemperatures. Expand

Continental-pelagic carbonate partitioning and the global carbonate-silicate cycle.
TLDR
Model results suggest that carbonate deposition patterns established during the Cenozoic may be pushing the Earth system from the continental to the pelagic mode on a time scale of 10(8) yr, with a possible consequent order-of-magnitude increase in the metamorphic CO2 flux to the atmosphere. Expand
