Iron isotope fractionation has emerged as a critical tracer for deciphering the complex biogeochemical cycling of iron in soils. This process, whereby natural variations in the relative abundance of ...

The land-water ecotones, such as coastal areas, wetlands, riverine zones, and aquifer recharge areas, serve as important transition zones, fostering intricate biogeochemical processes between ...

Earth’s Mantle Nitrogen Content Is Comparable To That Found In Its Nitrogen-Rich Atmosphere. Mantle Nitrogen has been proposed to be primordial or sourced by later subduction, yet its origin has not ...
