Basalt weathering laws and the impact of basalt weathering on the global carbon cycle
TLDR
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.About:

The technological and economic prospects for CO2 utilization and removal
Cameron Hepburn,Ella K. Adlen,John Beddington,Emily A. Carter,Emily A. Carter,Sabine Fuss,Niall Mac Dowell,Jan C. Minx,Pete Smith,Charlotte K. Williams +9 more
TL;DR: The capture and use of carbon dioxide to create valuable products might lower the net costs of reducing emissions or removing carbon dioxide from the atmosphere, but barriers to implementation remain substantial and resource constraints prevent the simultaneous deployment of all pathways.

A review of mineral carbonation technologies to sequester CO2
TL;DR: This work investigates the current advancement in the proposed MC technologies and the role they can play in decreasing the overall cost of this CO2 sequestration route and finds the value of the products seems central to render MC economically viable in the same way as conventional CCS seems profitable only when combined with EOR.

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.
Journal ArticleDOI
Mineral Carbonation of CO2
TL;DR: CarbFix as discussed by the authors injects CO2 into permeable basaltic rocks in an attempt to form carbonate minerals directly through a coupled dissolution-precipitation process.

Permanent storage of carbon dioxide in geological reservoirs by mineral carbonation
Jürg M. Matter,Peter B. Kelemen +1 more
TL;DR: In this paper, the authors show that the rate of carbonate mineral formation is much higher in host rocks that are rich in magnesium- and calcium-bearing minerals, such as basalts and magnesium-rich mantle rocks that have been emplaced on the continents.

The Cenozoic evolution of the strontium and carbon cycles: relative importance of continental erosion and mantle exchanges
Yves Goddéris,Louis François +1 more
TL;DR: In this paper, a model of the major geochemical cycles coupled with an energy balance climate model is used to explore the possible causes of the Mesozoic-Cenozoic fluctuations in the seawater 87Sr86Sr isotopic ratio.

The role of basalt weathering in the Sr isotope budget of the oceans
A.S Taylor,Antonio C. Lasaga +1 more
TL;DR: Using a coupled fluid flow-mass transfer model to calculate the Sr flux resulting from the weathering of the young Columbia River basalts, it can be shown that the dissolution of the reactive phases in the extensive continental flood basalt could have caused the significant inflection in the marine Sr isotope record that occurred approximately 15 million years ago as mentioned in this paper.

Water-rock interactions in tropical catchments: field rates of weathering and biomass impact
TL;DR: In this article, a combination of mass-balance calculations and water sample geochemistry allows the computation of weathering rates for small watersheds in the basaltic area of Ribeirao Preto (Parana, Brazil).

Regional correlation of Grande Ronde Basalt flows, Columbia River Basalt Group, Washington, Oregon, and Idaho
TL;DR: In this paper, major-element chemistry and relative stratigraphic position within the polarity intervals are used to identify and correlate individual flows and sequences of flows within the Grande Ronde Basalt on a regional scale.

Uranium colloidal transport and origin of the 234U–238U fractionation in surface waters: new insights from Mount Cameroon
Jean Riotte,François Chabaux,Marc F. Benedetti,Aline Dia,Martine Gérard,Jacques Boulègue,J. Etame +6 more
TL;DR: The role of colloids on the transport of the uranium isotopes was evaluated in this paper, showing that colloid-associated and solute U isotopes exhibit a significant isotopic difference.
