Global silicate weathering and CO2 consumption rates deduced from the chemistry of large rivers
TL;DR: In this article, newly compiled data on the 60 largest rivers of the world are used to calculate the contribution of main lithologies, rain and atmosphere to river dissolved loads, and the relationship between the chemical weathering rates of silicates and the possible controlling parameters are explored.
Journal ArticleDOI
Basalt weathering laws and the impact of basalt weathering on the global carbon cycle
TL;DR: In this paper, the chemical weathering of basalts and the flux of carbon transferred from the atmosphere to the ocean during this major process at the surface of the Earth were investigated.
Journal ArticleDOI
Chemical composition of suspended sediments in World Rivers: New insights from a new database
TL;DR: A new database on the chemical composition of suspended matter in World Rivers, together with the associated elemental fluxes is presented, showing that riverine fluxes are similar to anthropogenic fluxes, which casts light on the effect of human activities on the cycles of trace elements at the Earth's surface.

Chemical and physical denudation in the Amazon River Basin
TL;DR: In this article, major and trace element data on the suspended and dissolved phases of the Amazon River and its main tributaries are presented, where the proportions derived from different sources are calculated.

Erosion of Deccan Traps determined by river geochemistry: impact on the global climate and the 87Sr/86Sr ratio of seawater
Céline Dessert,Bernard Dupré,Louis François,Louis François,Jacques Schott,Jérôme Gaillardet,Govind J. Chakrapani,Sujit Bajpai +7 more
TL;DR: In this paper, the impact of the Deccan Traps on chemical weathering and atmospheric CO2 consumption on Earth is evaluated based on the study of major elements, strontium and 87Sr/86Sr isotopic ratios of the main rivers flowing through the traps, using a numerical model.

Geomorphic/Tectonic Control of Sediment Discharge to the Ocean: The Importance of Small Mountainous Rivers
TL;DR: In this paper, data from 280 rivers discharging to the ocean indicates that sediment loads/yields are a log-linear function of basin area and maximum elevation of the river basin.
Journal ArticleDOI
Chemical differentiation of the Earth: the relationship between mantle, continental crust, and oceanic crust
TL;DR: In this paper, the average chemical compositions of the continental crust and the oceanic crust (represented by MORB), normalized to primitive mantle values and plotted as functions of the apparent bulk partition coefficient of each element, form surprisingly simple, complementary concentration patterns.
Journal ArticleDOI
Variation of seawater 87Sr/86Sr throughout Phanerozoic time
TL;DR: In this paper, a curve of seawater 87Sr/86Sr versus geologic time through the Phanerozoic is presented, which provides a basis for dating many marine carbonate, evaporite, and phosphate samples.
Journal ArticleDOI
Elemental mass-balance of material carried by major world rivers
Jean-Marie Martin,Michel Meybeck +1 more
TL;DR: In this paper, an estimate of average river particulate matter (RPM) composition was based on analyses of more than 40 elements in the Amazon, Congo, Ganges, Magdalena, Mekong, Parana and Orinoco rivers, covering the whole spectrum of morphoclimatic features.
