Sulfur isotope data for: Intermediate sulfidation type base metal mineralization at Aliabad-Khanchy, Tarom-Hashtjin metallogenic belt, NW Iran

These data represent sulfur isotope analyses of chalcopyrite from a base metal deposit in the Aliabad-Khanchy area in northwestern Iran. Rock samples were collected from outcrops, and chalcopyrite was separated for analysis by hand picking. The separates were analyzed for the ratio 34-S/32-S by elemental analyzer-isotope ratio monitoring mass spectrometry. Standardization was performed by analyzing internationally-distributed standards along with the unknowns and then normalizing the results to the accepted values for the standards.
