Abstract :

Khoonik area, south of Birjand, northeast Iran, is one of the promising areas for epithermal gold mineralization. The area comprises outcrops of Eocene to Late Eocene volcanics intruded by a microdiorite unit. Preliminary prospecting in the area using ASTER mineral mapping (SAM) provided satisfactory results when checked with field observation. The identified alteration zones include advanced argillic, intermadiate argillic, propylitic, alunitization and silicification. Maximum dispersion of gold and arsenic in the stream sediment samples is correlated with the alteration zones. Mineralization types are hydrothermal breccia, disseminated and veinlet. Nature of the mineralization, the extent of silicic and argillic alteration types and their relation with lithology and structural geology are evidences indicating the presence of an epithermal gold deposit.
