Fingerprinting Kinetic Isotope Effects and Diagenetic Exchange Reactions Using Fluid Inclusion and Dual‐Clumped Isotope Analysis
; ; ; ; ; ; ; ; ; (Geochemistry, Geophysics, Geosystems, 2023-02-09)
Geochemical analyses of carbonate minerals yield multiple parameters which can be used to estimate the temperature and water composition at which they formed. Analysis of fluid trapped in minerals is a potentially powerful ... -
Laboratory Assessment of the Impact of Chemical Oxidation, Mineral Dissolution, and Heating on the Nitrogen Isotopic Composition of Fossil‐Bound Organic Matter
; ; ; ; ; ; ; ; ; ; ; (Geochemistry, Geophysics, Geosystems, 2022-08-19)
Fossil‐bound organic material holds great potential for the reconstruction of past changes in nitrogen (N) cycling. Here, with a series of laboratory experiments, we assess the potential effect of oxidative degradation, ... -
Recordings of Fast Paleomagnetic Reversals in a 1.2 Ma Greigite-Rich Sediment Archive From Lake Ohrid, Balkans
; ; ; ; (Journal of Geophysical Research: Solid Earth, 2019)
State-of-the-art paleoclimate research strongly depends on the availability of time-equivalent markers as chronological control to disentangle interrelationships in the climate system from regional to global scale. Geomagnetic ... -
Sporopollenin chemistry and its durability in the geological record: an integration of extant and fossil chemical data across the seed plants
; ; Beer, Maxine A.M.; ; Woutersen, Amber; Bogota‐Angel, Giovanni; ; Fraser, Wesley T.; Lomax, Barry H.; Huang, Huasheng; Sciumbata, Matteo; He, Huajie; Dupont‐Nivet, Guillaume (Palaeontology, 2021-01-31)
Sporopollenin is a highly resistant biopolymer that forms the outer wall of pollen and spores (sporomorphs). Recent research into sporopollenin chemistry has opened up a range of new avenues for palynological research, ... -
Teeth of Past and Present Elephants: Microstructure and Composition of Enamel in Fossilized Proboscidean Molars and Implications for Diagenesis
Białas, Nataniel; Prymak, Oleg; Singh, Ningthoujam Premjit; Paul, Debajyoti; Patnaik, Rajeev; (Geochemistry, Geophysics, Geosystems, 2021-04-22)
Enamel as hardest biological tissue remains unaltered for millions of years and is therefore an excellent archive for studies on paleodiet, paleoecology, paleoclimate, paleoenvironment, biomechanical, and evolutionary ...
