Exploration of iron and chromite by geological and geophysical studies in Shovin area, Sistan and Bluchestan Province

Authors

Abstract

The study area is geologically and potentially capable of mineralization of iron and chromite, and thus, there are many mines and ore deposits of such ore minerals at short distances in the area.  This area is located nearby ophiolite and ultramafic assemblages in which considerable mines of iron and basic metals are observed and explored. Considering the economical concentration potential of iron and chromite in this area, some studies on a regional scale have previously been performed. Here, we have investigated Shovin mineralized area for further exploratory studies. Our magnetometric studies reveal that no iron-rich ore deposit is observed in this area and the high magnetic intensities indicate the presence of magnetic minerals in ultramafic rocks. High magnetic intensities are due to the presence of a dyke and the existence of ultramafic rocks. The presence of a buried mass with a density of about 4.4 g/cm3 is proved based on modeling of the gravity data obtained from the area. Thus, the presumption of the presence of a chromite mass in the study area is highly possible.
