Calcite Precipitation at Captain Jack Superfund Site, Boulder County, CO

Detailed Description

Interactions between water and minerals in the subsurface (including efflorescent sulfate salts and calcite such as this sample from the Big Five adit) are a primary control on water quality in mining environments. Research is evaluating the importance of these minerals in generating acid mine drainage.
