GEOLOGIC QUESTIONS ABOUT: DEPTH TO BEDROCK

How far from the surface is a rock layer? Where is a postulated fault? What are the subsurface elastic properties of a zone or layer? Where is the water table? Where is a channel cutting into the bedrock? Why don't my borehole picks of top of rock make sense? Where is the location of a weak zone, a soft layer or fault gouge zone?

GEOPHYSICAL SOLUTIONS:

GOOD METHOD: Electromagnetics for geologic structure (M-4)

BETTER METHOD: DC Resistivity(M-3))

BEST METHOD: Seismic Refraction (M-1)

Honorable mention: Gravity (M-6)
