Fluvial sandstone beds in Petrified Forest Member of Upper Triassic Chinle Formation, northwest New Mexico and northeast Arizona
- Geological Survey, Denver, CO (USA)
Distribution, lithology, and fluvial style of sandstone and conglomerate beds in the upper part of the Petrified Forest Member of the Chinle Formation provide new interpretations of Chinle stratigraphy and environments of deposition. Newly described sandstone beds near Taaiylone, Mitchell Draw, and Crazy Woman Canyon in the Grants-Gallup region, lie, respectively, 60, 110, and 180 m stratigraphically above the top of the widespread Sonsela Sandstone Bed. The Correo Sandstone Bed, exposed on the south flank of Mesa Gigante, 75 km east-southeast of Grants, has been miscorrelated with the sandstone at Mitchell Draw. Subsurface data indicate that the Correo occurs stratigraphically above the other sandstone beds, near the top of the Petrified Forest Member.
