Kandik River sedimentary overlap assemblage 

(Cretaceous, Jurassic, and Late Triassic) 

(East-central Alaska, unit KJs)

Consists chiefly of Late Triassic, Jurassic, and Early Cretaceous shelfal shale and quartzite (Glenn Shale, 
Keenan Quartzite) overlain by mainly graywacke turbidites and nonmarine molasse strata that were 
recycled from foreland basin deposits (Biederman Argillite, and Kathul Graywacke). Generally broadly 
folded with local, small isoclinal folds. Locally isoclinally folded and with low-grade regional 
metamorphism. Kandik River assemblage thrust onto miogeoclinal margin of western North America along 
northwest-dipping thrusts. Kandik River assemblage interpreted as a faulted overlap assemblage originally 
deposited on Porcupine terrane to northwest, and possibly also on North American craton margin to east. 
Structurally overlain by Angayucham and Porcupine terranes along northwest-dipping thrusts.
