Abstract

The study area is located 35 km SE of TORBAT-E-HEYDARIEH in Central Iran structural zone. The oldest rocks are upper Triassic slates and slaty shales, Jurassic quartz bearing sandstone and conglomerate . The lower Cretaceous transgressive sequence including conglomerate, sandstone, micritic to dolomitic limestone, tuff, limestone, dolomite, shale with interbedded limestone and green shales has overlain the Jurassic rock units by unconformity. Geochemical studies on Fe-Mn ore composition. Include study of MAJOR ELEMENTS, TRACE ELEMENTS and rare earth elements. In the MAJOR ELEMENTS study, Mn/Fe, Si/Al and Na/Mg ratios are used. These ratios indicate formation of Fe-Mn ore by hydrothermal processes in shallow marine environment. All trace element diagrams show low contents of elements such as Ni, Co, and Cu in the Fe- Mn orees. Therefore, deposits of the study area in this diagram locate in the area of hydrothermal deposits. The REE patterns for the Fe-Mn ores from the area have more similarity to those of hydrothermal deposits.
