   Abstract
   The systematic geochemical exploration of Chadegan sheet was done based on a contract between Kah-Iran Consulting Engineers and GSI at 2003. The map is part of 1:250000 Shahrekord quadrangle located in the Isfahan and Chahar Mahal and Bakhtiari provinces.
   The goal of the project is systematic geochemical studies on the scale of 1:100000 in conformity with duty of Consultant Services in the contract. In order to achieve the above objectives, experts during a planned program and by using available information including airborne geophysics and geological maps, at first designed sampling points on topographic maps of the scale 1:50000. In the next step in the field 800 stream sediment samples and 30 duplicate samples (80 mesh) were taken and analyzed by ICP-MS method in the Amdel laboratory of Australia. After receiving the results and data processing, preliminary anomalies were determined.
   The second phase includes traveling to the filed and controlling anomalies with taking heavy minerals and rock samples from the main branches simultaneously.
   After preparing the results of rock samples and studying heavy minerals, the data combined with each other to definite identified anomalies in terms of importance and priority.
   13 zones indicated in the Chadegan sheet that twelve of them are located in the sedimentary rock units and only an anomaly is in the Sanandaj-Sirjan metamorphic rocks (amphibole schist, gneisses and crystalline limestones).
   Important mineralization and deposits generally occur in the Upper Cretaceous rocks and the oxide carbonate horizon that sometimes overlaps with volcanism. The type of deposit is vein-mineralization of lead, zinc and some copper oxide, gangue iron, manganese silica and carbonate. Barite is more abundant minor minerals.
   Although the highest detected grade is 1%, but other samples can lead to higher amounts of lead and zinc and copper to achieve. The mineralization correlates with lead and zinc state in the lower Cretaceous such as Ahangaran mine, and Lakan deposit; a similar trend towards Aligudarz, Golpayegan, Arak and Malayer. Amounts of lead and zinc, although in the further tests may be high values, but because being a vein type likely to be of no economic justification.
