Autor: I. E. Kohl, Jeanine L. Ash, Barbara Sherwood Lollar, Edward D. Young, Thomas Giunta, Oliver Warr
Publikováno v: Geochimica et Cosmochimica Acta. 294:315-334
This study applies a combined isotope and doubly-substituted isotopologue (‘clumped’) methane approach to samples collected over a 9-year long-term experiment at the Kidd Creek scientific observatory located 2.4 and 2.9 km depth below surface, co

Almahata Sitta (AhS), an anomalous polymict ureilite, is the first meteorite observed to originate from a spectrally classified asteroid (2008 TC(3)). However, correlating properties of the meteorite with those of the asteroid is not straightforward

Exchange catalysis during anaerobic methanotrophy revealed by 12CH2D2 and 13CH3D in methane

The anaerobic oxidation of methane (AOM) is a crucial component of the methane cycle, but quantifying its role in situ under dynamic environmental conditions remains challenging. We use sediment samples collected during IODP Expedition 347 to the Bal

Iron isotope constraints on planetesimal core formation in the early solar system

Publikováno v: Geochimica et Cosmochimica Acta. 246:461-477
We determined the Fe isotope fractionation between the metal and silicate phases of two aubrite meteorites, Norton County and Mount Egerton. We find that the metallic phase is high in 57Fe/54Fe with respect to the silicate phase, with Δ57Femetal-sil

Deep-sea hydrothermal fluids are often enriched in carbon dioxide, methane, and hydrogen. Methane effuses from metal-rich black smokers such as the Rainbow hydrothermal field, at temperatures higher than 200 °C. At the Lost City field, CH4 emanates

Methane sources and sinks in continental sedimentary systems: New insights from paired clumped isotopologues 13CH3D and 12CH2D2

Publikováno v: Geochimica et Cosmochimica Acta, 245 . pp. 327-351.
Stable isotope compositions of methane (δ13C and δD) and of short-chain alkanes are commonly used to trace the origin and fate of carbon in the continental crust. In continental sedimentary systems, methane is typically produced through thermogenic

Nucleosynthetic isotope anomalies show that the first few million years of solar system history were characterized by two distinct cosmochemical reservoirs, CC (carbonaceous chondrites and related differentiated meteorites) and NC (the terrestrial pl
