Hydrogeochemistry and geothermal characteristics of the White Lake basin, South-central British Columbia, Canada

摘要

Hydrogeochemistry and geothermal characteristics of the Tertiary White Lake basin are described in order to provide constraints on the hydrogeology and thermal regime of the basin. The basin can be divided into three flow subsystems on the basis of chemical and iso- topic variations. The groundwaters evolve chemically from young Ca-Mg-HCO_3 type waters in the shallow surficial sediments to Na-dominated waters in the deeper intermediate systems. Surface waters and shallow groundwaters collected from wells completed in overburden have Undergone extensive evaporation as evidenced by their enriched δ~18O and δ~2H composition.
