Quartz concentration as an index of sediment mixing : hydraulic mine-tailings in the Sierra Nevada, California

Auteur :
JAMES, L. A.

Description :
Hydraulic gold mining delivered large volumes of sediment to northern California stream channels from 1853 to 1884. Distinctive quartz composition of this sediment allow development of a sediment mixing index for determination of tailings concentrations in contemporaneous and reworked deposits. This index reveals patterns of sediment mixing in the Bear River, California over the last 100 years.
