Analytical Characterization Approaches to Measure Prebiotically Relevant Compounds in High Salinity Impact-Induced Hydrothermal Systems

by Keith Cowing

Experiments exploring potential emergence-of-life chemistry in a laboratory setting critically depend on simulating realistic early-Earth environments. Such experimental conditions include the implementation of controlled high temperatures and pressures, anoxic gas […]
