During 1999, DC resistivity data using various configurations with differen
t spacings over buried dykes were collected with the SYSCAL-R1 PLUS resisti
vity instrument in the Al Quweira area, southwest Jordan, as part of an eco
nomic deposit and ore exploration project. The objective of the study was t
o evaluate the resolution of resistivity techniques in detecting and locati
ng anomalies of vein-like bodies in the Al Quweira area and other locations
throughout our geophysical survey program. Resistivity measurements were c
arried out utilizing the Wenner array, the single-pole array, the half-Wenn
er array and the half-Schlumberger array. The results obtained based on 2-D
inversion of field data demonstrated a strong correlation between resistiv
ity anomalies and a subsurface vein-like body. A resistive vein exhibits ma
rkedly high-resistivity anomalies. In addition, the survey indicated that r
esistive vein-like bodies can be detected and located at shallow depths bel
ow the surface using the resistivity profiling method. Correlation between
field results obtained from different resistivity profiling arrays shows th
at the half-Schlumberger array is the most reliable one since it showed det
ails over the buried dyke that were only poorly indicated by other arrays.
