Granitoids of Sanandaj-Sirjan Zone that are concurrent with Cimmerian Orogeny (178-160 Ma) belong to ilmenite series (S-type): investigation of reason for lacking the porphyry tin mineralization
ntroduction The granitic rocks are divided into magnetite and ilmenite series (Ishihara 1977), coinciding spatially with the I-type (εNdi0; (87Sr/86Sr)i~0.704-0.706) and S-type granites (εNdi<0; (87Sr/86Sr)i~0.708-0.765), respectively (Takahashi et al., 1980). Most porphyry Sn deposits are assoc...
