Abstract
The following geophysical well log measurements were made in eleven drill holes above the Colorado School of Mines Experimental Mine at Idaho Springs, Colorado: (1) acoustic velocity (2) resistivity, (3) caliper, (4) gamma-gamma density, (5) neutron-thermal neutron, (6) gamma ray, (7) induced polarization (IP), (8) self potential (SP), and magnetic susceptibility. The density and acoustic velocity logs indicate extensive fracturing in each of the drill holes. Variations in the relative amount of felsic or mafic mineral components in the rocks can be inferred from the magnetic susceptibility and gamma ray well log responses. Zones containing metallic sulfide mineralization are interpreted from the IP well log response.
