In many sedimentary uranium deposits, close relationships between uranium and organic
matter can be observed. They may be statistical, spatial or chemical. Such relationships …

Methylphenanthrene (MP), dimethylphenanthrene (DMP), and trimethylphenanthrene (TMP)
distributions have been determined in crude oils and rock extracts from different origins at …

The thermal maturity and organofacies sensitivity of polycyclic aromatic compound (PAC)
distributions was explored by examination of the aromatic fractions of solvent extracts from a …

Thermal decomposition of siderite has been proposed as a source of magnetite in martian
meteorites. Laboratory experiments were conducted to evaluate the possibility that this …

This study proposes a new approach to investigate primary migration in petroleum source
rocks under laboratory conditions. It was conducted on organic carbon-rich, type II kerogen …

The thermodynamic stabilities of methyldibenzothiophene (MDBT) isomers and the
mechanisms of 1, 2-methyl shift, methylation and demethylation have been systematically …

The intricate relationship between climate and vegetation dynamics, particularly during the
late Paleozoic ice age marked by multiple icehouse-greenhouse transitions, is a compelling …

The thermodynamic stability of methylphenanthrene isomers and the kinetics of reactions
involved in their natural destruction/formation have been studied via molecular modelling …

Whole oil GC-MS was used to characterize selected polynuclear aromatic hydrocarbons
(PAH) in a suite of marine crude oils derived from source rocks deposited under different …

Biomarkers in coal can evolve dramatically in terms of their concentration and distribution
during coalification, limiting their use in source allocation of coal-derived pollution. Here we …
