Summary:
Named from Kuzitrin River, Seward Peninsula, AK, along whose lower course, unit is well exposed. Typically exposed in Kigluaik Mountains, near their northern limit, in belt which runs parallel to axis of range and cut by tributaries of Kruzgamepa River. Composed of well-jointed graphitic quartz-schist, intercalated graphitic slates, and calcareous, amphibole, and chloritic schists. Estimated thickness is between 2000 and 3000 ft. Overlies Kigluaik series (new). Underlies Nome series (new). Map legend shows age is Paleozoic or older.

Summary:
Kuzitrin series of Brooks and others (1901) revised as Kuzitrin formation. Type locality [designated] along Kuzitrin River. Consists for the most part of graphitic quartzites and siliceous schists. May exist as undifferentiated member of Nome Group west of Grand Central River. Stratigraphic chart shows Kuzitrin as basal pre-Silurian(?) unit in Nome Group. Overlies Kigluaik group. No direct evidence for its age, but Kuzitrin may belong near base of Ordovician though probably could be either Cambrian or Algonkian.
