OF-97-07 Stratigraphic and Structural Cross Sections of the Coal-Bearing Williams Fork Formation, Mesaverde Group, Colorado


Includes two plates. Plate 1: Genetic-stratigraphic cross section of the coal-bearing Williams Fork Formation, Piceance and Sand Wash Basins, Colorado. Plate 2: Cross section indicating missing and duplicated strata due to faulting (9S-91W through 9S-89W) Piceance Basin Colorado. Uses genetic stratigraphy to correlate Williams Fork coal zones between Sand Wash and Piceance Basins. Cross sections delineate major depositional systems and show rationale for coalbed methane target generation and resource estimates. 2 plates. Digital PDF download. OF-97-07D
