Stratigraphy
Stratigraphy comments: The Pitkin Fm. overlies the Fayetteville Fm. This boundary is gradational and for this study was taken to be the point at which shale partings between the limestone beds were not more than several inches thick. The Pitkin limestone ranges in thickness from 0 to over 60ft. in northeastern Oklahoma. The Pitkin is absent north of Wagoner and Cherokee counties due to truncation below lower Pennsylvanian strata. In the study area, the Pitkin represents the uppermost Mississippian and is unconformably overlain by lower Pennsylvanian Morrowan Series. |
Lithology and environment
Primary lithology: | wackestone |
Secondary lithology: | mudstone |
Includes fossils? | Y |
Lithology description: The Pitkin limestone is dark gray, bioclastic and ooltic limestone with lesser amounts of mudstone and wackestone. | |
Glacial or sequence phase: | regressive |
Geology comments: In general, rocks dip away from the axis of the uplift which runs from Tahlequah northeast to the St. Francis Mountains. The Pitkin Limestone iss discontinuously exposed at the surface in the area due to northeast trending faulting and folding of the strata. The Pitkin Limestone thins to the north and northeast due to regional truncation during early Pennsylvanian time and tends to thicken to the south and southwest towards what was a basin at the time of depostion. |
