Mineralogy and alteration in polymetallic zone

The outcrop of stratigraphic rock units of many geological periods can be seen in Ardabil province. These outcrops can be divided into two groups of pre-Paleocene and post-Paleocene rock units. Most outcrops belong to Tertiary sedimentary volcanic units. The study area is located in the northwest of Ardabil province and north of Meshginshahr city with a distance of ۱۱۵ km to Ardabil in the geographical area with lengths of ۴۸°۳۰′−۴۷°۳۰′ north and latitudes ۳۸°۳۰′−۳۹°۰۰′ east. Niaz Gholi-Moshiran exploration area is located in the northwest of Ardabil province in ۱: ۱۰۰,۰۰۰ of Lahroud sheet. Geologically, most of the area is covered with Paleocene-Eocene rocks, which consist of volcanic sections with andesite, tephrite and trachyandesite fragments, which are observed along with the andesite-tephrite pillow lava. According to this sheet, the oldest rock units in the study area are related to the Cenozoic (Eocene), which consists of volcanic rocks with andesite, tephrite, trachyandesitic-hyaloclastite. The youngest stone units are the young thrusts and alluvial fans of the present age.
