Abstract

The study area is a part of Central Iran and Bafq Block. The general of this block is SE-NM and its length and width are 400 and 100 km, respectively. The oldest terrains of Central Iran and the metamorphic basement make a major part of the study area. After Assyntic Orogeny, other younger formations of Infracambrian, Paleozoic and Tertiary have covered the Precambrian in some parts. Late - Proterozoic rifting has been one of the major events affecting the structural evolution of the central triangle of Central Iran and formation of ore potentials and widespread mineralizations. The evidences show that the continental rifting had never been grown up to an oceanic type. In this Ph. D. Thesis, all the different types of structures, including lineaments and central type structures have been studied using remote sensing techniques, aeromagnetic methods and field checks. This approach has been done in a Geographic Information System (GIS) to help to make the best decision. In this way, the NW trending lineaments have been considered as the main granitization lines. The other group of the lineaments with the general NE trend has been responsible for the metasomatic activities. These two groups of lineaments are called "Basement faucts". There are two major N-S and E-W trending lineaments named "Deep crustal faults". The activities of these LINEAR STRUCTUREs together with central type structures have provided special paths and corridors for heat flow, magma itrusions and transmission of minerals-bearing fluids. On the other hand, the sodic METASOMATISM has been the major phenomenon affecting the Uranium mineralization in the study area. All the known ore deposits (in general) and DarAnjir-Khoshumi ore field (in details) have been studied for understanding and approving the relation between structural patterns and metallogeny in the area. As a result, N-S and E-W trending lineaments, their intersection points with each other and with central type structures seem to be the main places of ore indications and occurrences. Therefore, these specific points could be selected confidentially for further exploratory works in the future.
