Dizaj and Qotur are two sheets in the Khoy quadrangle at northwest of Iran. These sheets that contain ophiolite and colored melange are the host of amphibolite, schist, marble, and volcanic rocks. Ultrabasic rocks of ophiolitic zone include dunite, periodotite and serpantitnite associated with pillow basalt, and Cretaceous limestone. Sedimentary rocks include shale, siltstone, sandstone, limestone, radiolarite and dolomite. Important potential minerals in these sheets involve:
- Au in the listvenites that is up to 820 ppm.
- Manganese in the pillow basalts (10-20%) with iron (42%)
- Chromite up to 54% in the ultrabasic rocks with magnesite and iron mineralization.
- Cu mineralization in the meta-volcanic and amphibolite rocks, silicic serpentinites and Tudan granodiorite up to 5.1%.
- Nickel in the weathered serpentinites with iron oxide. The nickel and cobalt contents reach to 2000 ppm and 4000 ppm respectively.
- Non-metallic minerals include silica, talc, magnesite and feldspar in ophiolitic and metamorphic rocks.
