Abstract: The 2015 Gold King Mine (GKM) spill into the Animas River, Colorado, USA, is an opportunity to evaluate acute mine discharge into a chronically metal-rich system. We measured metals, C and N isotopes in soil,… read more here.

Abstract: Abstract Reconstructing the environmental conditions that supported early life on Earth relies on well-preserved geochemical archives in the rock record. However, many geochemical tracers either lack specificity or they are affected by post-depositional alteration. We… read more here.
