Isotope stratigraphy: Insights on paleoclimate and formation of nitrate deposits in the Atacama Desert, Chile

Arid environment nitrate deposits are economically important and analogous to Martian environments, but their formation is poorly understood. Detailed N, O, and C isotope stratigraphy suggests Atacama Desert nitrate deposits form abiologically by differential leaching during hyperaridity (precipitat...
