...M. D. Lewan; M. J. Kotarba ABSTRACT Hydrous-pyrolysis experiments at 360°C (680°F) for 72 h were conducted on 53 humic coals representing ranks from lignite through anthracite to determine the upper maturity limit for hydrocarbon-gas generation from their kerogen and associated bitumen (i.e...

... the arid western United States and, in particular, the Hanford site. Results illustrate the release of U from these sediments is kinetically controlled, and low water contents encountered within the Hanford vadose zone result in the formation of mobile–immobile water regimes, which isolate a fraction...

..., and crystallization. In this paper, we document a clear case of liquid immiscibility in an intrusive body of tholeiitic gabbro in the Siberian large igneous province, using textures and compositions of millimeter-sized silicate melt pools in native iron. The native iron crystallized from a metallic iron liquid, which...

... sediments belong to the wet red beds type according to Schneider et al. (2010) and were deposited during the late early Cisuralian wet phase D ( Roscher and Schneider, 2006 ). Apart from common tiny rootlets, this formation basinwide rarely shows any evidence of plant growth. In this respect, the Chemnitz...

... organic matter deposited in an oxidizing environment that produces mainly gas ( Tissot et al., 1974 ). These kerogen types were described based on atomic H/C and O/C ratios obtained from elemental analysis. The H/C and O/C ratios are typically plotted on Van Krevelen diagrams, originally derived from...
