The Catak iron deposit consist of magnetite-bearing lenses distributed along the northeast-trending contact of the north end of. the Egrigoz granitic massif in Kutahya Province. Area A is near the northeast end of the deposit and contains three main irregular magnetite lenses. A body of talc-silicate hornfels, almost surrounded by quartzite and schist , lies a short distance from the contact with quartz monzonite and contains the magnetite-bearing lenses west-northwest to northwest-trending structural grain is expressed by schistosity, joints, shears, lithologic contacts and outcrop patterns, although the mineralized rock and general intrusive contact trend northeast.
The ranges of the average content of Fe, Si, and S, determined from drill data are 33.54-53.95 percent; 5.86-12.25 percent; and. 8.33-9.49 percent, respectively.
