Whole-rock geochemistry and crystal chemistry of apatite at intrusive suites of the Qeynarjeh-Angouran district (west of Zanjan): an approach to the identification of skarn-causati... by Afsoon Dastour, Ebrahim Tale Fazel, Ashraf Torkian

“…Results and discussion The intrusive suites of the studied area include the Gharavol-Khane quartz diorite intrusion with granular and porphyroidic textures, the Kuh-e Belghais granite porphyry with porphyry, granular and graphic textures, and the Qeynarjeh granodiorite, has microgranular, porphyroidic, and graphic textures. In terms of alumina saturation index (ASI), the study intrusive suites belong to the metaluminous to slightly peraluminous series and I-type granite and have calc-alkaline to shoshonitic affinity. …”
