New Elements issue: Cratons to Continents 

Archean continental crust is present on every continent, but does not constitute a dominant part of any continent’s surficial exposures. Nevertheless, Archean cratons are the longest-­lived coherent physical structures on Earth. Viewed holistically, they comprise a welded com­bination of continental crust and as sub­continental lithospheric mantle keel. They are survivors of what may, or may not, have been a more numerous and varied population of protocontinents. Many of these crustal blocks have origins in the Hadean and have survived for billions of years through many super­continent cycles...

Spicule morphology impacts stable silicon isotopic composition of sponge archives

The stable silicon isotopic composition of siliceous sponge skeletal elements, spicules, forms a potential proxy for past dissolved silicon (DSi) concentrations of bottomwaters. Field-based studies have shown that there is...

A baseline for the Sn isotopic composition of the upper continental crust

We report high precision Sn isotopic compositions, expressed as δ122/118Sn relative to the NIST3161a standard, for the fine grained matrix of 24 glacial diamictite composites. The diamictites were deposited...

Neoarchean marine chemical sediments as archives of Hadean silicate differentiation

Planetary differentiation had a profound influence on the geochemical signature of the Earth’s silicate reservoirs. Some of the early created complementary reservoirs dissipated with time (e.g., Bennett et al., 2007)...

Shape and depth of ocean floor profoundly influence how carbon is stored there

[] The movement of carbon between the atmosphere, oceans and continents—the carbon cycle—is a fundamental process that regulates Earth's climate. Some factors, like volcanic eruptions or human activity, emit carbon dioxide into...

Dust Declines in Parts of Asia May Be Caused by the Warming Arctic

[Eos] For years, the amount of dust in the atmosphere over West and South Asia has decreased. Now, research suggests that rising temperatures in the Arctic may be the cause. As Arctic ice melts, darker ocean and land surfaces reflect less sunlight...
