Geologic setting

Geologic description

A stream sediment sample in upper Glacier Creek contained 164 ppm Pb, 367 ppm Zn, and 12 ppm As (Hudson and Wyman, 1983). Follow-up reconnaissance soil sampling in the headwaters of Glacier Creek identified this occurrence. The soil sample collected here contained 51 ppm Cu, 420 ppm Pb, 1,520 ppm Zn, 10 ppm Ag, and 62 ppm As. Monument Mountain is underlain by a polydeformed metapelitic schist that may be Precambrian in age but the bedrock of Glacier Creek is a metasedimentary sequence of Lower Paleozoic age (Till and others, 1986). The Paleozoic metasedimentary rocks locally include felsic metavolcanic rocks in areas peripheral to Kiwalik Mountain. Float of very fine-grained, siliceous, tan-weathering metasediment (tuff or exhalite ?) has been observed in the headwater gravels of Glacier Creek (T. L. Hudson, unpublished data, 1982).
