The Naghadeh metamorphic complex at the West-Azerbaijan Province is located at termination of the NW Sanandaj-Sirjan Zone. Major varieties of the metamorphic rocks in this area are: amphibolites, greenschists, marbles and metaperidotites. The metaperidotites are classified into two groups, serpentinised metaperidotites and serpentinites. Orthopyroxene, clinopyroxene, olivine and spinel are the ...

Metamorphic rocks that mostly consist of amphibolite, amphibole schist, garnet hornblendite and rarely metamorphosed chemical and terrigenous sediments are found in the ophiolitic complex of north Torbat-E- Heidarieh. Thermobarometry calculations of amphibolite samples indicate temperature higher than 800 °C and pressure less than 5 Kb. Metamorphic conditions of  amphibole schist and garnet hor...
