Several tonalitic-trondhjemitic intrusion bodies have been injected into the metamorphic complex consisting of greenschist, blueschist and grt-amphibolites in the soltanabad area (ne sabzevar). thermobarometry of these bodies that carried out by whole rock chemical chemistry, the occurrence of magmatic garnet and epidote as well as geochemical characteristics of amphibole and plagioclase point to crystallization temperature of 665 to 749 °c and pressure between 8 to 11 kbar. in order to estimate the depth of emplacement and to obtain the more precise crystallization temperature, temperature and pressure conditions of metamorphic aureole and reaction rim of the outer margins of the intrusion bodies, were calculated. on the base of obtained data, the conditions of pressure and temperature of emplacement and solidifications of intrusion bodies are compatible with the scenario of partial melting of young subducted oceanic lithosphere at depth of a hot subduction zone.
