Resolving varve and radiocarbon chronology differences during the last 2000 years in the Santa Barbara Basin sedimentary record, California
TL;DR: In this paper, the validity of age model assumptions is tested including whether the regional reservoir age of surface waters was invariably 641±-119 years through time, and whether SBB laminae couplets are consistently annual varves and counted with sufficient precision.

Extreme climatic conditions recorded in Santa Barbara Basin laminated sediments: the 1835–1840Macoma event
TL;DR: Dall et al. as discussed by the authors found evidence for a sudden local extinction of macrobenthos by suffocation at a depth of 55-57 cm below the surface of the seafloor.

Natural seepage of shale gas and the origin of “eternal flames” in the Northern Appalachian Basin, USA
TL;DR: A spectacular "eternal flame" in western New York State marks a gas macroseep of dominantly thermogenic origin emanating directly from deep shale source rocks, which makes this a rare case in contrast to most Petroleum Seepage Systems where gas derives from conventional reservoirs as discussed by the authors.

Chemical compound classes supporting microbial methanogenesis in coal
TL;DR: In this paper, a comparison of the molecular compositions of the initial organic extracts with their biodegraded residues after incubation of the bioreactors for 24 weeks indicated that biodegradation of n-alkanes and aromatic hydrocarbons occurred concurrently, whereas hopanes proved to be far more refractory.

Porosity and pore size distribution in mudrocks from the Belle Fourche and Second White Specks Formations in Alberta, Canada
TL;DR: The distribution of porosity was examined on seven drill cores from west-central Alberta encompassing the Belle Fourche and Second White Specks Formations as discussed by the authors, and the in-core variations in total porosity were mainly related to mesoporosity and macroporosity.
