Abstract

Ghazan-Khanik complex is a small mafic-ultramafic intrusive body with Permian age at the extremity of NW of the Sanandaj-Sirjan zone, has intruded into the Precambrian metamorphic rocks. Field studies, geochemistry mineral compositions and assemblages of them demonstrate this complex has four lithological zones. The lower zone of non-layered gabbro is the fine-grain gabbronoritic component and non-mineralized. The second zone include of non-apatite ultramafic, clinopyroxenite, verlite and minor amounts of dunite with high proportion of Fe-Ti oxide (25-30%). The pure Fe-Ti oxide mineralization (with highly 90%) occurred as sill-like cumulates parts within this ultramafic zone. The third zone consists of layered gabbro, which is occurred Fe-Ti oxide mineralization (0. 5-5%) only in the apatite-rich mafic parts. The upper zone includes the anorthosite and pegmatite gabbro with 0-2% Fe-Ti oxide. Based on this studies for establishment of rich Fe-Ti oxide layers, two processes are involved; (1) enrichment in residual melts which is derived from basaltic parental magma and (2) injection of Fe-Ti oxide immiscible melts into mafic-ultramafic crystallizing mass.
