Carbon isotope ratios of organic matter in Bering Sea settling particles: Extremely high remineralization of organic carbon derived from diatoms
diatoms coccolithophores carbon isotope organic carbon remineralization rain ratio
2017/4/10
The carbon isotope ratios of organic carbon in settling particles collected in the highly-diatom-productive Bering Sea
were determined. Wet decomposition was employed to oxidize relatively fresh orga...
Stepwise combustion analyses of distinct nitrogen isotopic compositions on Paleoproterozoic organic matter
nitrogen isotopic composition Paleoproterozoic stepwise combustion method kerogen Gunflint Formati
2017/4/11
Nitrogen isotopic analyses were conducted on two kerogenous samples from the Gunflint Formation (ca. 1.9 Ga)
using the stepwise combustion technique to evaluate a potential analytical problem for the...
Photochemical, microbial and metal complexation behavior of fluorescent dissolved organic matter in the aquatic environments
photodegradation microbial degradation metal complexation
2017/4/12
Chemical properties and reactivity of fluorescent dissolved organic matter (FDOM) are examined in this paper. They
are key issues to understand the biogeochemical processes in the aquatic environment...
Can pressure promote hydrocarbon generation from organic matter?—New experimental proof
pressure pyrolysis natural gas carbon and hydrogen isotopes
2017/8/9
In order to investigate if pressure can increase the yield of the yield of methane and gaseous hydrocarbon as a whole, both anhydrous and hydrous isothermal pyrolysis experiments were performed on Fus...
Hydrogen Isotopic (D/H) Composition of Organic Matter During Diagenesis and Thermal Maturation
deuterium, fossil fuel isotope exchange isotope fractionation catagenesis
2014/4/8
Changes in the D/H ratio of sedimentary organic matter (SOM) during thermal maturation have been difficult to interpret because the effects of hydrogen exchange and
kinetic fractionations are c...
