Resistivity


Line-Emerson



The top panel shows the raw data, with west on the left. the middle panel shows the predicted data from the model which is shown
in the bottom panel.

Line-Road




The panels are the same quantities as in Line-Emerson. In this case the line east on the left.

Ground Pentrating Radar (GPR)

ABOVE GPR profile along Line-Emerson with 100 Mhz,
1m antennas. The width of the section is 38.4m, and
the mapped Emerson Fault in is the middle of the
section (trace 584). The vertical scale is time in
millionths of a sec.
ABOVE A CMP section near Line-Emersion. The maximum
offset is 37.5. Note the horizontal axis is half-offset.
Time is in millionths of a sec.
ABOVE A 100 MHz profile along Line-Road, going
from East to West. The section is 97.5m wide, the
mapped fault trace is in the center (trace 2970).
ABOVE A 50 Mhz, 2m antenna profile E->W along
Line-Road. The section is 47.5 wide and the
fault is in the middle.
