The metabasite rocks from north of Shahrekord, which is a part of structural zone of Sanandaj-Sirjan, are undergone medium temperature – high pressure metamorphism (eclogite facies). These rocks then were subjected to a retrograde metamorphism (amphibolite facies). A distinct compositional zoning is preserved in fresh garnets which are formed during eclogite facies. The compositional or growth zoning in these eclogite rocks shows clockwise P-T-t path.  In the beginning of metamorphism, P and T increased up to reach to the peak of high pressure metamorphism, then P decreased while the T was increasing during uplift and decompression. These growth stages indicate that P_max was not contemporaneous with T_max during eclogite facies metamorphism of the metabasites from North of Shahrekord, in Sanandaj - Sirjan Zone
