Tannin diagenesis in mangrove leaves from a tropical estuary: a novel molecular approach
Peter J. Hernes,Ronald Benner,Gregory L. Cowie,Miguel A. Goñi,Brian A. Bergamaschi,John I. Hedges +5 more
TL;DR: Molecular-level condensed tannin analyses were conducted on a series of mangrove ( Rhizophora mangle) leaves at various stages of decomposition in a tropical estuary.
Journal ArticleDOI
Selective organic matter preservation in ''burn-down'' turbidites on the Madeira Abyssal Plain
TL;DR: In this paper, the terrestrial organic component in the unoxidized Madeira Abyssal Plain turbidites is 13C-enriched owing to a significant C4 contribution, and a 13Cdepleted component of the terrestrial signal is selectively preserved in the process.
Journal ArticleDOI
A case of post-depositional aerobic degradation of terrestrial organic matter in turbidite deposits from the Madeira Abyssal Plain
TL;DR: In this paper, a set of oxidized and unoxidized sediment intervals from the f-turbidite identified in two piston cores from the Madeira Abyssal Plain (MAP) was analyzed for calcium carbonate, total organic carbon (TOC), total nitrogen (TN), stable carbon composition of TOC (δ13C toc ), total hydrolyzable amino acids (THAA), total neutral sugars (TSUG), lignin phenols (LIG), two different lipid biomarkers of marine phytoplankton origin and vascular plantwax
Journal ArticleDOI
Factors controlling the burial of organic carbon in laminated and bioturbated sediments off NW Mexico: Implications for hydrocarbon preservation
TL;DR: In this article, a suite of box and piston cores strategically located on the shelf-slope rise with respect to the intense oxygen minimum in this region, indicating that the preservation of oil-prone kerogen in productive margin settings does not appear to be restricted to sediments deposited under conditions of low bottom water O2 concentrations.
