Abstract

      The epithermal Au-Cu system of kudkan , west of Qaeh zari and  Kudakan village anomaly  is located in north part of Lut Block in Central Iran (Southern Khorasan). Mineralization features in study area, are mostly include veins that follow structural features with NW-SE trend and is hosted in  acidic- intermediate volcanic host rocks (andesite, trachy andesite, rhyolite) with Eocene age. Alteration zones include: moderate-advanced argillic, silicification, quartz- sericite- pyrite, quartz- iron oxide- carbonate and propylitic. Veins mineralization include: Quartz, sericite, pyrite and clay minerals. Based on fluid inclusions in quartz in west of Qaleh zari (anomaly zone 1), mineralization occurred in 109-429 ᵒC (mainly 100-300 C) and salinity between 0.2–9.7 wt.% NaCl equiv. Studies in this area  indicates low-moderate sulfidation mineralization in west of Qaleh zari. Also minerlogical and alteration evidences can indicate mineralization related intrusive bodies in anomaly zone 2. This resalts can help to new minerali zation zone in this area.
