Geochemical Evolution News Today

Scientists at Yale and SwRI reveal a new theory explaining how precious metals found their place in Earth's mantle, rewriting cosmic narratives.

Research into the deep biosphere requires an understanding of both the microbial community at a given site and the geochemical and hydrological factors that support that microbial community. To highlight the interplay between geochemistry and microbiology in these deep environments, we characterized the hydrogeologic and geochemical systems of a 2.7 Ga banded iron formation within the Canadian Shield in the Soudan Underground Mine State Park in Minnesota, USA, a site known to host a lithotrophic...
