Summary:
In this report, White applies the name Kittanning to several lithologies. In Beaver Co., Kittanning (Industry) sandstone and shale is 42 to 50 ft thick. At Industry, on Ohio River, it is 50 ft thick and forms massive vertical cliff. Underlies Kittanning fire clay and lies 30 ft above Vanport limestone. Kittanning (New Brighton) fire clay underlies Kittanning group. Kittanning group is a coal group that extends from top of Upper Kittanning coal to top of Buhrstone iron ore overlying Ferriferous (Vanport) limestone. Kittanning (Ferriferous) shale and ore consists of dark sandy shales with nodular iron ore, 35-40 ft thick, that overlies Lower Kittanning coal (may represent Johnstown cement bed).

Summary:

Summary:
Kittanning sandstone consists of coarse-grained to pebbly sandstone, 25-40 ft thick. Underlies Middle Kittanning coal and lies above Lower Kittanning coal. Exposed in small ravine between village of Worthington and Buffalo Mills, and extends to western edge of Worthington (town was built upon it). [Probably was not meant to be same Kittanning as defined by White, 1878; its position as defined here would make it younger.]

Summary:
In standard section for southwestern PA, both Kittanning and Clarion sandstones of Allegheny group lie between Lower Kittanning and Clarion coals. Because the sandstones are normally separated by Vanport limestone, which is absent in Fayette Co., it is difficult to determine whether sandstone lying below Lower Kittanning coal is Kittanning or Clarion sandstone; because sandstone commonly occurs in upper part of interval, it is here called Kittanning. Average thickness is about 10 ft.
