| Abstract | ||
| With respect to the vast area of Iran and extensive mineral potential zones (existence of Urumiyeh–Dokhtar volcanic belt) and the need for identifying and management of these deposits implies the use of GIS. Using GIS not only organizes the information related to mineral exploration but also has the ability to produce and integrate information layers in different models with more precision and speed and supports spatial decision makings. In this article mineral potential map of Now Chun porphyry copper prospect has been produced in detailed stage. Main steps of mineral potential mapping include: identify mineralization recognition criteria, information preparation and structuring, weighting and producing criteria maps, Integration of criteria maps and results evaluation. Used layers in this study include rock type, fault, alteration, mineralization indicators, anomaly zone of Chargeability and Apparent resistivity and metal factor, anomaly of Copper and Molybdenum and Cu-Mo additive indexes. | ||
