Composition and facies variations in mid-cretaceous gates formation coals, Northeastern British Columbia : implications for interpretation of paleo-wetland environments and assessment of coalbed methane characteristics
… data indicate that the maceral compositional variations are at least as significant as coal rank in determining coal bed methane characteristics. Compositional differences between lithotypes reflect differences in vegetation, accumulation rate and degree of plant decomposition. Lateral and …

High-Resolution Correlation Using Geophysical and Geochemical Methods on Three Cambrian Drumian Marine Sedimentary Successions in The House Range Embayment, Western Laurentia
… and uncertain. The complex lithological variations, the absence of lithostratigraphic and other reliable biostratigraphic markers, and the widely-spaced sampling and coarse correlation among HRE sections, have contributed to such uncertainty. This study focuses on regional high-resolution …

SOURCE AND MATURATION OF HYDROCARBONS IN THE FRIO FORMATION OF THE HUMBLE FIELD, SOUTHEAST-TEXAS GULF COAST BASIN
… with the transitional depositional source facies concluded from the geochemical inversion and further supporting the modeling result. However this does not rule out the possibility that the hydrocarbons of the Humble field were generated from the Midway, Eagle Ford, and Woodbine formations, …

Stratigraphic architecture of a shallow-water delta deposited in a coastal-plain setting: Neslen Formation, Floy Canyon, Utah
… channel to the delta front. Upward and lateral facies variations of the delta stratigraphy are evident. The feeder channels contain fine-grained, cross-stratified sandstone. These channels transfer longitudinally to the axial parts of mouth bars that are composed of amalgamated fine-grained, …
