Abstract :

Knowledge of the location of the blind fault and revealing fault length in urban areas are so critical. Moreover, recognizing and direct study of faults' location calls for selecting a proper approach to study the faults due to areas being covered with thick quaternary sediments and lack of faults outcrop in many areas. In doing so, one of the commonest methods is using geophysical methods. The study explored the blind faults of Banesh Plain in Fars, Iran using geoelectrical sampling with a Schlumberger array and integrating it with field sampling and direct observations. Accordingly, 30 soundings and 10 profiles were developed in this regard, and sections and pseudo-sections were analyzed. The results showed the existence of two fault zones along the northeast-southwest and northwest-southeast, and it seems that the conduction of groundwater in the mentioned area is under the influence of these two main zones.
