ABSTRACT: Our study area “Tafresh” is located in the sedimentary-volcanic belt. This
work was carried out as systematic for surveying ore potentials at Tafresh base
on the geology, geochemistry, laboratories studies, remote sensing, and
tectonic. According to study of 109 samples, most of the area’s mineralization
has been associated with Dacite, Diorite, Tonalite intrusive massive, Andesitic
dykes which are related to operation of thrust and strike slip faults. Also, most
of these ore deposits had been concentrated at sedimentary rocks of Cretaceous
that involves Limestone and Shale in the Southwest and Andesite to Andesitic
Basalt at the Northern of Tafresh area. Most of the alterations zones
associated with mineralization are androgenic like Argillic, Propylitic,
Sericitic, and siliceous alterations that have appropriate adaptation with
area’s major faults as well. Eventually, based on the geochemical studies and
incorporating all data by GIS software, Tafresh has remarkable concentration of
Cu and Au ore deposits that are recognized as Skarn and Hydrothermal ore
deposits which are related to fluids flowing from intrusive massive and dykes.
