A new estimate of detrital redox-sensitive metal concentrations and variability in fluxes to marine sediments
TLDR
In this article, an extensive study of soils across the continental United States and their elemental concentrations was conducted, and the authors found large deviations from accepted crustal averages in redox-sensitive metals (Fe, Cr, U, V) compared to typical detrital tracers (Al, Ti, Sc, Th).About:

The iron paleoredox proxies: A guide to the pitfalls, problems and proper practice
Robert Raiswell,Dalton S. Hardisty,Timothy W. Lyons,Donald E. Canfield,Jeremy D. Owens,Noah J. Planavsky,Simon W. Poulton,Christopher T. Reinhard +7 more
TL;DR: A recent review as discussed by the authors highlights the importance of robust Fe-based measures of local redox that, when combined with elemental mass balances and isotopic proxies dependent on those local conditions, can shed light on the global redox state of the oceans through time and related implications for the history of life on Earth.

Microbial Community Responses to Vanadium Distributions in Mining Geological Environments and Bioremediation Assessment
Baogang Zhang,Song Wang,Muhe Diao,Jie Fu,Miaomiao Xie,Jiaxin Shi,Ziqi Liu,Yufeng Jiang,Xuelong Cao,Alistair G.L. Borthwick +9 more
TL;DR: Li et al. as mentioned in this paper reported a systematic investigation into vanadium distributions and microbial communities in soils, water, and sediment from Panzhihua, China, and revealed the biogeochemical fate of vanadium in regional geological environments and suggests a bioremediation pathway via native vanadium reducing microbes.

Redox-sensitive trace metals as paleoredox proxies: A review and analysis of data from modern sediments
TL;DR: In this article, the authors report a new compilation and analysis of modern trace-metal enrichment data for a range of marine depositional environments, including euxinic basins, continental margin upwelling settings, and normal oxic settings.

Autotrophic Vanadium(V) Bioreduction in Groundwater by Elemental Sulfur and Zerovalent Iron.
TL;DR: It is demonstrated that efficient V(V) bioreductions can be coupled with bio-oxidation of elemental sulfur (S(0)) or zerovalent iron (Fe(0)), and the V (V) removal efficiencies reached 97.5 ± 1.2% and 86.6 ± 2.5% within 120 h using S(0) and Fe(0), respectively.

The effects of diagenesis on geochemical paleoredox proxies in sedimentary carbonates
Ashleigh von S Hood,Ashleigh von S Hood,Noah J. Planavsky,Malcolm W. Wallace,Xiangli Wang,Xiangli Wang +5 more
TL;DR: In this paper, the variability in uranium isotopes, trace metal and rare earth element (REY) concentrations in carbonate successions that have undergone several common types of diagenetic alteration was explored.

The continental crust: Its composition and evolution
TL;DR: In this paper, the authors describe the composition of the present upper crust and deal with possible compositions for the total crust and the inferred composition of lower crust, and the question of the uniformity of crustal composition throughout geological time is discussed.

Composition of the Continental Crust
Roberta L. Rudnick,Shan Gao +1 more
TL;DR: In this paper, the present-day composition of the continental crust, the methods employed to derive these estimates, and the implications of continental crust composition for the formation of the continents, Earth differentiation, and its geochemical inventories are discussed.
Journal ArticleDOI
The composition of the continental crust
TL;DR: In this paper, a new calculation of the crustal composition is based on the proportions of upper crust (UC) to felsic lower crust (FLC) to mafic lower-crust (MLC) of about 1.6:0.4.

Distribution of the Elements in Some Major Units of the Earth's Crust
Karl K. Turekian,K. H. Wedepohl +1 more
TL;DR: A table of abundances of the elements in the various major units of the Earth's lithic crust with a documentation of the sources and a discussion of the choice of units and data is presented in this article.

Trace metals as paleoredox and paleoproductivity proxies: An update
TL;DR: In this paper, a synthesis of the use of selected trace elements as proxies for reconstruction of paleoproductivity and paleoredox conditions is presented, and the combined used of U, V and Mo enrichments may allow suboxic environments to be distinguished from anoxic-euxinic ones.
