Abstract
In 1981 and 1982 intensive observations of the geomagnetic field were carried out in a possible seismic gap region in the western part of the North Anatolian Fault Zone to trace on active fault and also to accumulate geomagnetic data for earthquake prediction research. The data of magnetic anomalies obtained from profile measurements across the fault were interpreted to reveal an anomalous magnetic structure associated with the active fault. In order to confirm our results thus derived in the Iznik-Mekece area, similar observations were also made at Ismetpasa where fault traces are well known as well as creep for the North Anatolian Fault Zone.It is concluded that highly magnetized dike-like bodies exist extensively along active fault lines in the North Anatolian Fault Zone. This characteristic feature can be utilized for studies of active fault location and also for tectonomagnetic studies.Keywords
