Abstract
Biga Peninsula is one of the tectonically active regions in Northwestern Anatolia which
the middle strand of the North Anatolian Fault Zone is crossed over by it. This work is
aimed to model the subsurface geological structures via vertical electrical sounding (VES)
and self-potential (SP) datasets collected from the relatively less known Southern part of
the Biga Peninsula. The vertical electrical sounding (VES) and self-potential (SP) datasets
collected near the Erecek village of Çanakkale city were inverted by the LevenbergMarquardt algorithm. Four profiles were generated covering some VES points to reveal
the geological model. In addition, resistivity distributions at 10, 100, 200, 500, and 1000
meter depth levels were calculated. Thus, the iso-3D resistivity distribution was easily
observed. Based on the VES findings, three main geological units were defined; two
groups of volcanic units and a metamorphic basement. Besides, WSW-ENE and NNE-SSW
trending two normal faults that have possibly water content were observed. One of them
was also detected from the self-potential profile data inversion results. As a result,
possible main fault locations and tectonic structures that may be associated with
groundwater containment have been described using the findings of both two geoelectrical methods.
