Determination of Th-REE mineralization type using network modeling in Chapdoni-Posht-e-Badam complex, Central Iranian structural zone

Abstract

The Chapdoni-Posht-e-Badam complex is located in the Central Iranian structural zone and the northeast of Yazd province. This complex is one of the areas with high potential for thorium-rare earth elements mineralization in Central Iran. In this research, the network modeling method has been used to determine the type and potential of Th-REE mineralization in the study area. Different methods such as geochemistry, geophysics, remote sensing, field observations, and laboratory works have been used, and different criteria have been considered for scoring. After applying the mentioned methods, creating a database, and combining multiple layers, the mineralization model or possible deposit types have been determined. This research uses a network method to integrate different data layers and model them to produce a mineralization potential map. The results obtained for different types of mineralization models were combined in the form of final modeling, and a comprehensive map of mineralization potential was prepared. Finally, mineralization types related to granite, metasomatism, and metamorphism were determined for thorium and rare earth elements in the Chapdoni-Posht-e-Badam complex. The mineralization potential of thorium-rare earth elements in the center and south of the study area is more than in other places.
