Abundances of Uranium and Thorium Elements in Earth Estimated by Geoneutrino Spectroscopy
(American Geophysical Union, 2022-08-11)The decay of the primordial isotopes 238U, 235U, 232Th, and 40K has contributed to the terrestrial heat budget throughout the Earth's history. Hence, the individual abundance of those isotopes are key parameters in ... -
Unexpected Repartitioning of Stratospheric Inorganic Chlorine After the 2020 Australian Wildfires
(American Geophysical Union, 2022-07-18)The inorganic chlorine (Cly) and odd nitrogen (NOy) chemical families influence stratospheric O3. In January 2020 Australian wildfires injected record-breaking amounts of smoke into the southern stratosphere. Within 1–2 ... -
Organosulfur Aerosols Likely Carried Sulfur MIF Signatures in the Early Earth’s Atmosphere
(American Geophysical Union, 2023-10-16)Signatures of mass-independent fractionation (MIF) of sulfur in Archean sulfide and sulfate minerals are widely thought to record an anoxic early Earth’s atmosphere. While experiments of ultraviolet irradiation of SO2 ...
