... in the western part of the area. The Alapah Limestone (Upper Mississippian), 600-1950 ft thick, rests disconformably on the Wachsmuth Limestone. Where the Wachsmuth is absent, the Alapah rests conformably on the Kayak(?) Shale. The Wahoo Limestone (a new formation of Pennsylvanian(?) and Permian age), 0-1400 ft...

... the Sadlerochit high to paleotopographically lower areas 65 km to the southwest. The southward paleoslope is documented by onlapping geometry, erosional topography, and lateral facies variation. Twelve surfaces of subaerial exposure were identified in the Alapah Limestone and six in the Wahoo Limestone. Two can...

... in the central Brooks Range, the phosphatic unit occurs within the Alapah Limestone; in the Kelly River allochthon, it forms the uppermost part of the Kogruk Formation ( Dumoulin et al. 2014 ; Fig. 3 ). Where most tightly dated, the phosphatic unit is early Chesterian (late Middle Mississippian), based...

... and consist of the Utukok and Kogruk Formations. The Utukok Formation is an impure limestone with disseminated and interbedded noncarbonate mud and quartz-rich silt and sand. Clean carbonate predominates in the overlying Kogruk Formation but has been widely altered to dolostone and chert. Deep-water strata...

The Lisburne Group conformably overlies the Endicott Group and consists mainly of platformal limestone, with lesser dolostone ( Bird and Molenaar, 1987 ). Note...

.... In this analysis, we attempt to reference cement formation to the initial period of fracture opening. Samples 2–4 were collected from the Mississippian Alapah Limestone. Sample 3, from the south limb of an isoclinal anticline, contains examples of fracture sets 2 and 3 ( Figure 5 ; Table 1 ). Fracture set 2...
