a total of 40 samples from carbonates and 8 samples from silicate rocks were analyzed from the sangan iron skarn deposit to examine behavior of the oxygen and carbon isotopes. the higher values of ?18o are from metamorphic calcite and dolomite and lower ones are from granitic rocks. although the ?18o and ?13c values of calcite and dolomite in marble yield the highest values in the sangan deposi...

The Tang Zagh iron deposit is located about 117 km Northeast of Bandar Abbas, Hormozgan Province in the structural folded-thrusted zone of the Zagros basin. Iron mineralization occurs in the form of iron oxides (hematite) within the salt dome and/or in fractures and between the layers of the younger strata with the Tertiary age. Based on the microscopic studies, dolomitic fragments of the host ...
