Foraminiferal zonation and carbonate facies of the Mississippian and Pennsylvanian Lisburne Group, central and eastern Brooks Range, Arctic Alaska
The Lisburne Group carbonates of the central and eastern Brooks Range contain foraminiferal assemblages assigned to zones of Osage [late Tournaisian], Early Mississippian, to Atoka [early Moscovian], Middle Pennsylvanian age. Representatives of both Eurasiatic and American cratonic microfaunas permit correlation with the original Carboniferous type sections in western Europe as well as with the standard Mississippian and Pennsylvanian sequences in the Midcontinent region of North America. Correlation anomalies in the lower part of the sequence are discussed.
