|Location and accuracy||The Boundary occurrence, known in 1981 (Elliott and Koch, 1981, p. 8, loc. 14) only from a U.S. Bureau of Mines claims map (U.S. Bureau of Mines, 1979), probably is a placer deposit on the Unuk River approximately 1.5 mile below the Alaska-British Columbia boundary. The location is probably accurate within about a quarter of a mile.|
Geologic descriptionThe country rocks in, and immediately upstream from, the area of this placer(?) occurrence are Tertiary or Cretaceous granodiorite and quartz diorite; Mesozoic or Paleozoic metasedimentary and metavolcanic rocks and minor marble; and Eocene leucocratic quartz monzonite and granodiorite (Elliott and Koch, 1981; Koch, 1996). No other geologic information about this property was publicly available in 1981 (Elliott and Koch, 1981, loc. 14).
