Subtask Objectives

Subtask Statement of Work

Subtask Objectives

Regional geophysical, geochemical, remote sensing, and geologic data exist at regional and state scales but it is unclear whether the resolution of these data can be used to accurately characterize the geoenvironmental footprint of mineral deposits. The subtask objective is to create a logical and repeatable procedure that leads to geoenvironmental maps at regional to state scales. Maps will portray the environmental footprint of mineral deposits.

Statement of Work

Airborne geophysical signatures over mineralized volcanic and plutonic rocks in southwest Colorado will be interpreted in an environmental context by establishing relationships between physical rock properties that cause the anomalies to geochemical properties that are the source for either positive and negative effects on the environment. Specifically, numerous samples that have been analyzed for acid neutralizing capacity (ANC), net acid production (NAP), magnetic susceptibility, and electrical resistivity will be analyzed to determine if a relationship exists for particular volcanic lithologies that have been altered to varying degrees.
