| The Monkman Pass area, underlain by an assemblage of Hadrynian to Upper
Cretaceous sedimentary rocks, contains 29 recorded mineral occurrences. This
assemblage, deposited on and to the west of the Ancestral North American craton, consists
mainly of continental margin and shelf facies rocks. Structurally, these rocks are part of
the Foreland Thrust and Fold belt. The southern limit of the Quintette
(093I 010, 011),
and the Monkman
(093I 013), Saxon
(093I 016), Belcourt
(093I 014) and Coal
Ridge (093I 019) coalfields are located in the northern and eastern part of
the map sheet. The coal measures in the area occur in the Cretaceous Fort St. John and
Bullhead groups, primarily in the Gates and Gething formations, respectively. Minor base
and precious metal mineralization, mainly copper, silver and gold, occur in the Lower
Cambrian Gog Group, in veins and stringers. Several phosphate occurrences (Wapiti,
093I 008)) are hosted in the Triassic Sulphur Mountain Formation. High quality quartzite
dimension stone occurs near Babette
Lake (093I 005).
