Stratigraphy and Structure of the Ekokpuk Creek Area, North-Central Brooks Range, Alaska

摘要

Sedimentary rocks of Devonian to Cretaceous age in the vicinity of Ekokpuk Creek in the north-central Brooks Range are deformed and displaced northward by northward-verging tight folds and thrust faults. Here the proximity of black chert to limestone, both of the Lisburne Group of Mississippian age, is probably the result of original deposition rather than the result of tectonic juxtaposition as has been previously postulated.
