AbstractAreas of known mineralization in Ordovician through Devonian rocks on eastern Cornwallis Island were visited as reconnaissance for a project that will address the genesis and geological controls on Zn-Pb mineralization within the Polaris zinc district and elsewhere in the Arctic Islands. Parts of the Thumb Mountain, Cape Phillips, Allen Bay, Barlow Inlet, and Disappointment Bay formations are host to Mississippi Valley-type mineralization, which is vari- ously localized by 1) normal faults, 2) facies boundaries, or 3) a major unconformity. Much of the mineralization is indicated by development of gossans, but some is present without any significant weathering features. The pres- ence of showings that completely lack galena and have only sparse Fe-sulphides suggests that there may be more than one mineralizing event or fluid source behind the various showing types in the area.
