   Favorable Mineral Potentials of the Nagisan Sheet
  
   Abstract
   The Nagisan sheet is located in the Jahanabad Quadrangle, 225 km away from southeast of Kerman, between 5830' to 59 eastern longitudes and 28 to 2830' northern latitudes. In this project we tried to identify important mineralized zones of the sheet with application of geochemical, geophysical, remote sensing, and field data.
   The area is situated in the Central Iran structural zone and its lithology includes tuff, andesite, trachy-andesite and so on, all of Tertiary and Quaternary. Dominant unit in the sheet is a lenticular granitic batholith that is 52 km long. It trends NE-SE. Brittle faults have two dominant trends including NW-SE and NE-SW. Airborne geomagnetic data show that the main anomalies are located in the northwestern margin of the sheet, near the Deh-Ashour, Godmahi and Ziaratshah villages and deep-seated faults having northwest-southeast trend. Based on the radiometry data, there is a radioactive mineral resource in the region.
   Geochemical data are also confirming the importance of these anomalies: Ziaratshah, west of Nagisan River, north of Abbasali strait, Dekan and Govinj which show argillic and propylitic alterations. Potassic and phyllitic alterations have lesser extent. Important anomalies are within argillic and propylitic alteration zones. Mineralization can involve porphyry copper, vein copper, skarn, polymetal and epithermal types that field studies proved the existence of a small-to medium porphyry deposit.
