| Abstract | Meager Mountain is the best explored of the geothermal systems in the Cascade and Garibaldi Volcanic Belts. Several fluid types are present, ranging from low temperature, high TDS fluids to high temperature, moderate TDS fluids. Na HCO3 - SO4 fluids and acid alteration have been found downslope of H2S fumaroles. Isotopic and chemical evidence indicate little mixing between fluid types. Fluid flow at Meager Mountain is confined to fractures separated by impermeable matrix blocks. The fractures are commonly filled by calcite precipitation caused by subsurface boiling. |
