Geologic reconnaissance of the Uzunpinar iron mine and vicinity, Kayseri Province, Turkey

The Uzunpinar iron mine consists of two pits. The lower, larger pit is situated at the edge of a valley and the smaller upper pit is 1.1 km to the southwest on a limestone ridge. The upper pit is near the northern end of a northeast-trending mineralized fault zone that consists of altered limestone, silicified rock, hematite, and some magnetite. The lower pit exposes a west-trending magnetite-hematite lens that is directly on line with the fault zone and probably is controlled by an extension of the fault zone.
