The study area is located in the Yazd Province, 130 Km away from the east of Yazd and 20 km away from east of Bafq. This area belongs to the Central Iran structural zone in which there are various mines such as apatite, iron, lead and zinc.
Geochemical survey is a method for identification of promising zones. Explorational activities in the Saghand-Poshte Badam and Bafq-Biabanak zones of the Central Iran, include two sheets of Esfordi and Bafq that contains diversified lithology and important mines, for example Choghart iron, Chadormalu, Kushk lead-zinc, Esfordi apatite and so on.
The geochemical survey was done at March 1999, during 30 days field visit under supervision of Mahmud-Reza Alavi-Naini. During the project, 843 stream sediment samples were taken and analyzed for 28 elements by ICP-Mass method.
The study was led to identification of several anomalies. The favorable mineralized zones include:
1- Northwestern corner, around the Sirusabad village, east and south of Kushk mine shows evidence of copper mineralization. Acidic plutons exist in the area.
2- Phosphor mineralization was seen in the S-SE of Gazestan village and also south of Esfordi. The Mn-mineralization in this area is also notable.
3- There are good iron anomalies in the Moshirabad village (north of Farak 1:50000 sheet), south of Sehchangan 1:50000 sheet, around Esfordi and the central portion of 1:50000 sheet of Sirusabad. All of these anomalies contain titanium.
4- Barite mineralization exists in the east and northeast of the area, south of Farak sheet.
