Geology

Alteration processes:

Specific data for bedrock in this drainage are not available but quartz monzonite (granite) and alaskite from this pluton are reported to be intensely altered to sericite, chlorite, and some epidote (Csejtey, Patton, and Miller 1971, p. D73). Float of tourmaline-rich granite samples from unidentified streambeds of eastern St. Lawrence Island have high (but unspecified) tin values (Patton and Csejtey, 1971, p. 7).
