Eclogites and blueschists of the Sistan Suture Zone, eastern Iran: A comparison of P-T histories from a subduction mélange

Significant differences exist between the peak-metamorphic P-T conditions recorded by samples from different lenses in the mélange, indicating that the lenses were detached from subducting lithosphere at different depths. P-T paths of eclogite-facies rocks were 'clockwise' with ca. 1.5 GPa of almost isothermal decompression.
