Landscape geochemistry near mineralized areas of Eastern Alaska with a focus on As and Sb
The Pogo lode gold deposit was discovered in eastern Alaska in the early 1990s. To characterize the effects of mineralization on the As and Sb signature of the area, prior to mine development, we evaluated the soil-vegetation-stream water system at several locations near and distal to the mineralized areas. Arsenic concentrations range from ＜1 to 14μg/L in stream water; ＜0.01 to 0.14mg/kg in willow leaves; and 3 to 410 mg/kg, 6.1 to 440 mg/kg, and 2 to 300 mg/kg for the A, B and C soil horizons, respectively. Sb concentrations range from ＜0.1 to 0.71 μg/L in stream water; ＜0.003 to 0.23 mg/kg in willow leaves; 0.4 to 24 mg/kg, 0.6 to 25 mg/kg, and 0.2 to 16 mg/kg for the A, B and C soil horizons, respectively. In general the highest concentrations of both As and Sb were found near mineralized areas.
