GEOLOGIC QUESTIONS ABOUT:
DENSITY
What is the density of the rock? Where are the low density portions of the stratigraphy? How does the density vary spatially? Where are the faults? Where are the abandoned-mine's air shafts? How can I find sinkholes or underground voids? Where is the gas in my well?
Geophysical Solutions:
GOOD METHOD: Ground Penetrating Radar(M-12)
BETTER METHOD: Seismic Refraction (M-1)
