Summary:
Pg. 33, 38, 207, and pl. XLA. Mingo formation of Pottsville group. Shales, sandstones, and coals, 950 feet thick, underlying Catron formation and overlying Hance formation in Cumberland Gap coal field. Top defined by base of Poplar Creek [Poplar Lick] coal in Log Mountains, and by base of Wallins Creek coal in Black Mountains. Base defined by base of Harlan coal to east, by base of Hance coal in central part of Cumberland Gap coal field, and by base of Bennett Fork coal at west. Correlated with upper part of Kanawha formation and lower part of Sewell formation. Age is Pennsylvanian.
[Named from Mingo Mountain, Claiborne Co., northeastern TN. Extends into southeastern KY.]
[Misprint (US geologic names lexicon, USGS Bull. 896, p. 1381): top of Mingo is placed at base of Poplar Lick coal, not Poplar Creek coal.]

Summary:
[See p. A37-A38, A43 (fig. 9). †Mingo Formation of Breathitt Group. In lower part of Breathitt Group, below the †Catron Formation and above the †Hance Formation, along Pine Mountain Fault, in southeasternmost Kentucky, and bordering area of Tennessee and Virginia. Is not formally abandoned herein but its use is clearly discontinued; it is not distinguishable on basis of lithic character and cannot be traced laterally with consistency. As originally defined, top was placed at base of Poplar Lick coal in the west and base of Wallins Creek coal in the east, which were thought to be correlative. Rice and Smith (1980) showed the Poplar Lick occurs as much as 350 feet below the Wallins Creek. Members of the †Mingo are transferred to the Breathitt Formation (reduced in rank to conform with USGS usage elsewhere).
The Mingo was formally abandoned by Rice and others in their glossary (1994, GSA Spec. Paper 294, p. 137, citing McDowell and others, 1985).]
