Abstract

With detection of the magnetic minerals along with the chromite, it is possible to prospect the chromite deposits. Chromite has no magnetic properties but from the genetic aspects, there is a close relation between chromite and magnetite. With this respect and the magnetic differences of chromite minerals with the country rocks, the effort was to prospect the chromite mineralization of 1: 50000 Abdasht sheet by the use of air born geophysical data. In the study of the geophysical air born of the area, the observed magnetic piles in the area has been investigated by using of the digital filters of reduce to pole, first and second derivations, analytical signals and upwards continuation on the map of the magnetic field of the total intensity. With the study of these maps and compare them with the area, especially ophiolite and ultramafic bodies and chromite-included areas have been studied and the final results are compared with the magnetic pattern and with respect to the maps of the vertical derivation and upwards continuation, 25 areas for the detailed exploration and field sampling area suggested in the entire sheet of the Abdasht.
