  • Project 6: The Environment of the Early Earth
    NAI 2013 Rensselaer Polytechnic Institute Annual Report

    This project involves the development of capabilities that will allow scientists to obtain information about the conditions on early Earth (3.0 to 4.5 billion years ago) by conducting chemical analyzes of crystals (minerals) that have survived since that time. Minerals incorporate trace concentrations of ions and gaseous molecules from the local environment. We are conducting experiments to calibrate the uptake of these “impurities” that we expect to serve as indicators of temperature, moisture, oxidation state and atmosphere composition. Our focus has been mainly on zircon, quartz, and apatite.
