Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Effect of Laboratory Reagents for Cleaning Modern Contamination on the δ<sup>15</sup>N Integrity of Nitrogen-Poor Samples. [PDF]
ABSTRACT Rationale Nitrogen isotope values have been widely used for tracing ancient biogeochemical processes, but contaminant‐sensitive materials, such as Precambrian sedimentary rocks, meteorites, or returned extraterrestrial samples, often have low nitrogen levels and are thus vulnerable to modern organic contamination.

The kerogen in pyrobituminous shale.
Kerogen is the name given to the organic matter which occurs in coal and pyrobituminous shale. The correct adjective to describe a kerogen-containing shale is "pyrobituminous", which indicates that it gives an oil on pyrolysis or destructive distillation, - its most important property commercially. [...]

Molecular Weight Distribution of Kerogen with MALDI-TOF-MS [PDF]
Kerogen is an amorphous organic matter (AOM) in fine grain sediments, which produces petroleum and other byproducts when subjected to adequate pressure and temperature (deep burial conditions).

Three-dimensional molecular modeling of Dachengzi oil shale kerogen [PDF]
A three-dimensional (3D) molecular model of Dachengzi oil shale kerogen was constructed using quantitative 13C direct polarization/magic angle spinning solid-state nuclear magnetic resonance (DP/MAS SSNMR) data and accurate quantum chemistry methods. The

Red to Green: A Lipid Biomarker Record of Tonian-Ediacaran Algae in Siberia. [PDF]
ABSTRACT Multiple lines of evidence point to a major diversification of Eukarya in the late Tonian period, ca. 800–720 Ma ago. Regular steranes, lipid biomarkers primarily sourced from eukaryotes, are first unambiguously reported from multiple sites. Here, we present lipid biomarker stratigraphic records from two drill‐cores from the Lena‐Anabar Basin ...
