Abstract :
The study area is Sanandaj-Sirjan zone in Hormozgan province. The place has undergone great metamorphismand magmatism and is the most active structural region of Iran, from geological perspective. Magmatism andmetamorphism processes caused noticeable increase in the potentiality of the mineral elements in the region.Gold, iron, copper, chromite, porcelain and stone façade and silica are the main potential elements. The area ismainly formed by Paleozoic and Mesozoic rocks. According to geochemical studies of rocks and rivers, theamount of gold shows 4 times and coppers, 116 times of Clark enrichment limit. Based on the geochemical dataand XRD data analysis and the existence of the collection of minerals such as chlorite, epidote, albite, calcite,and pyrite, the possibility of having a zone of alteration zone propylitic is very high. Also, in some areas, due tothe abundance of epidote it is possible to find epidotic alteration. Penetration of Andezites into limestone rockscauses Pyrite and Hematite alteration. Due to the porosity of the limestone and the alterations mentioned, thelimestone (western part of the area) is a suitable context for copper and gold mineralization which needs furtherresearch.
