CORRELATION BETWEEN MINERALIZATION AND STRUCTURAL CONTROLS USING THE FRACTAL ANALYSIS OF FAULT DISTRIBUTION IN NORTHEAST OF IRAN
Abstract
The North part of Kashmar is located about 250 Km Southwest of Mashhad, Northeast Iran. It is part of the structural Darouneh fault zone and contains rhyolitic, andesitic, pyroclastic and lava flows. Based on results obtained from AFM and Miyashiro diagrams the igneous rocks classified as a subalkaline and calcalkaline. From the data obtained the Kashmar strike-slip fault geometry (distribution of shear fractures such as R,RЛґ,P surfaces, Riedel structures) plays an important role in controlling the location and emplacement of polymetal mineralization of copper, lead and zinc ore deposits. To show that the observed shear fracture surfaces are indeed not significantly different from classical Riedel shear pattern a fractal analysis has been done to compare field observations and classical Riedel shear pattern. The result shows that the estimated fractal dimension for schematic Riedel is about 1.17, which is in agreement with fractal dimension of field measurement.
