Sedimentology and petroleum occurrence, Schoolhouse Member, Maroon Formation (Lower Permian), northwestern Colorado
The Lower Permian Schoolhouse Member of the Maroon Formation forms a partly exhumed petroleum reservoir in the Eagle basin of northwestern Colorado. The Schoolhouse consists mainly of yellowish gray to gray, low-angle to parallel bedded, very fine to fine-grained sandstone of eolian sand-sheet origin; interbedded fluvial deposits are present in most sections. Geological and geochemical data sugges

Occurrence and geochemistry of natural gases, Piceance Basin, northwest Colorado
The Piceance basin is a hydrocarbon-rich province that has natural gas production from reservoirs ranging in age from Late Jurassic to Eocene and large undeveloped resources of natural gas in coal beds and tight sandstone reservoirs of Cretaceous age. Gases from all producing intervals are of predominantly thermal origin and become isotopically heavier (delta isotope{13}C[1]: -51.3 to -29.1 o/oo)

Coal and peat in the sub-Saharan region of Africa: alternative energy options?
Increased energy demand as a result of growth in population, trends to sedentation and urbanization, and the desire for improvement in living standards, coupled with apparent climatic changes, are reducing fuelwood availability and contributing to deforestation and desertification in the sub‐Saharan countries. In 14 of those countries, the transport, industrial, and electric power generation secto

Extensional faulting in the southern Klamath Mountains, California
Large northeast striking normal faults in the southern Klamath Mountains may indicate that substantial crustal extension occurred during Tertiary time. Some of these faults form grabens in the Jurassic and older bedrock of the province. The grabens contain continental Oligocene or Miocene deposits (Weaverville Formation), and in two of them the Oligocene or Miocene is underlain by Lower Cretaceou
