Summary
[edit]DescriptionMowry Shale (mid-Cretaceous; east of the Medicine Bow River, eastern Carbon County, Wyoming, USA) 4 (48689623826).jpg |
Shales in the Cretaceous of Wyoming, USA This is a weathered outcrop of Mowry Shale, a mid-Cretaceous unit having dark-colored siliceous shales. Exposures usually consist of fissile, chippy-weathering, whitish-gray shale. Fossil fish scales occur here. In Wyoming and Montana, the Mowry is a significant source rock for hydrocarbons. It's been calculated that about 12 billion barrels of oil have been generated by the Mowry in the deep subsurface of those two states (see summary in Bremer, 2016). Stratigraphy: Mowry Shale, mid-Cretaceous Locality: outcrop on the northern side of Route 30 / Route 287, between milepost 275 and 276, ~1.5 miles west of Fossil Bone Cabin, east of the Medicine Bow River, southern flank of the Como Bluff Anticline (= near the western nose of the anticline), eastern Carbon County, southeastern Wyoming, USA Reference cited: Bremer (2016) - Stratigraphy and Sedimentology of the Cretaceous of the Cretaceous Mowry Shale in the Northern Bighorn Basin of Wyoming: Implications for Unconventional Resource Exploration and Development.
