Structural Control on Epithermal Mineralization in the Troud-Chah Shirin Belt Using Point Pattern and Fry Analyses, North of Iran

摘要

The Troud-Chah Shirin belt, located in the Alborz magmatic belt, is one of several mineralized belt in Iran. Ore mineralization in this belt is controlled by faults and fractures. The spatial distribution of mineralization is the foremost concern in regional exploration and it could be considered as a very important tool in the investigation of mineral deposits. In this study, we use point pattern and Fry analyses to known occurrences and distribution of epithermal mineral deposits, and results show that structural controls play the major role in distribution of these ore deposits. A mechanism of structural controls on epithermal mineralization, which is involves a more-or-less regular T fractures of extension faults/fractures at and/or around intersections of F1 and F2 trending strike-slip faults/fractures. Spatial data and structural controls can apply for future exploration, for possibly undiscovered occurrences of epithermal ore deposits.
