Aeromagnetic interpretation and mineral investigations in the Ezine, Canakkale-Karabiga, Marmara, and Kapidag areas of northwestern Turkey

January 1, 1972

Aeromagnetic surveys and mineral investigations are planned or in progress in ten areas of northwestern Turkey (fig. 1). This report reviews results obtained from August 1967 to January 1, 1968, through aeromagnetic interpretation and field investigations in four of the areas (Areas 2, 3,4, and 5).

Aeromagnetic interpretation identified 27 prominent anomalies, 17 of which were checked in the field. The majority of these anomalies were found to be caused by minor amounts of magnetite in igneous rocks, including granite stocks, mafic flows, and mafic dikes. Other anomalies are caused by magnetite in metamorphic rocks or by topographic effects. However, massive magnetite boulders were observed in three adjoining localities (Anomalies E2, E3, and E4, fig. 2) in area 2, and magnetite partly replacing a limestone boulder was found in area 3 (Anomaly CK3, fig. 3). Further study of these magnetite exposures is planned.

In addition, two iron prospects and one lead prospect were briefly examined. All the prospects were considered small and not worthy of further study at this time.
