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.

Large igneous provinces and mass extinctions
TL;DR: In this paper, the authors compare the timing of mass extinctions with the formation age of large igneous provinces and reveal a close correspondence in five cases, but previous claims that all such provinces coincide with extinction events are unduly optimistic.

Effects of climate on chemical_ weathering in watersheds
Art F. White,Alex E. Blum +1 more
TL;DR: In this paper, the authors evaluated the effect of weathering on chemical weathering by correlating variations on solute concentrations and fluxes with temperature, precipitation, runoff, and evapotranspiration (ET) for a worldwide distribution of sixty-eight watersheds underlain by granitoid rock types.

Influence of late Cenozoic mountain building on ocean geochemical cycles
TL;DR: 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, whereas marine biogenic sedimentation dominates removal Dissolved fluxes in rivers are related to rates of continental weathering, which in turn are strongly dependent on rates of uplift.

The abundance of 13c in marine organic matter and isotopic fractionation in the global biogeochemical cycle of carbon during the past 800 ma
TL;DR: For the later Neoproterozoic, from 800 to 543 Ma (346 analyses), from the Cambrian through the Jurassic (1616 analyses), and from the Cretaceous and Cenozoic (2493 analyses) the abundance of 13 C in marine organic matter has been compiled as discussed by the authors.

On causal links between flood basalts and continental breakup
TL;DR: In this paper, a mixed scenario of active/passive rifting was proposed to account for these observations, and the authors found that an active component (a plume and resulting flood basalt) is a pre-requisite for the breakup of a major oceanic basin, but rifting must be allowed by plate-boundary forces and is influenced by preexisting heterogeneities in lithospheric structure.
