PrintWidespread and intense wildfires at the Paleocene-Eocene boundary
M.K. Fung, M.F. Schaller, C.M. Hoff, M.E. Katz, J.D. Wright

Discovery of impact spherules associated with the onset of the Carbon Isotope Excursion (CIE) that marks the Paleocene-Eocene (P-E) boundary (~56 Ma) indicates that the P-E transition was coincident with an extraterrestrial impact. Charcoal abundances increase >20 times background immediately above the P-E spherule layer at two Atlantic […]

GPL1905_abstract_100Zircon halogen geochemistry: Insights into Hadean-Archean fluids
H. Tang, D. Trail, E.A. Bell, T.M. Harrison

Understanding the distribution of halogens in rocks can potentially trace ancient lithosphere, hydrosphere, and atmosphere interactions. Although no sedimentary rocks older than 3.8 Ga are known, insights into sediment-atmosphere exchange on early Earth could be obtained from knowledge of halogen contents in ancient zircons. […]

GPL1903_abstract_100Oxidised micrometeorites as evidence for low atmospheric pressure on the early Earth
P.B. Rimmer, O. Shorttle, S. Rugheimer

Reconstructing a record of the partial pressure of molecular oxygen in Earth’s atmosphere is key for understanding macroevolutionary and environmental change over geological history. Recently, the oxidation state of iron in micrometeorites has been taken to imply the presence of modern Earth concentrations of oxygen in the upper atmosphere at […]

GPv7n2_cover_100CO2: Earth’s Climate Driver
Wally Broecker

In this new Geochemical Perspectives, Wally recounts the evolution of climate over Earth’s history in six brief episodes, from the early Earth and conditions on our planet under the faint young sun, through the current global warming challenge stemming from the burning of fossil fuels. Along the way Wally reviews some of the major evidence and enigmas of the geologic record and how these have revealed not only the climate of the past, but which processes were critical for this evolution. Through it all, Wally is careful to point out what we feel we now know, as well as research directions that might be most fruitful in the future. Written in a concise and easy to follow text, this should be an enlightening read for experts and novices alike.
