Qara Aqaj titanium potential is one of the two major known titanium resources in Iran. The main host rocks of the ore body are ultramafics including wehrlite and lherzolite with minor clinopyroxenite. Qara Aqaj intrusion is composed mainly of ultramafic-mafic rocks, layered gabbro, diorite, microdiorite and some monzonite and alkali syenite. This intrusion has intruded the basement complex (amp...
متن کاملApatite Application to Investigate Magmatic Evolution of Zouzan Granites, NE Lut Block
Apatite minerals of I-type Zouzan granitoids and typical garnet-bearing S-type granites have been analyzed by electron microprobe to define trace element concentrations and compare them in different granites. Zouzan granites are composed of apatites with lower Fe, Mn, Na and HREE and higher REE and ∑REE relative to S-type ones. Trace elements abundances of apatite often vary with some parameter...
متن کاملMineralogy from three peralkaline granitic plutons of the Late Permian Emeishan large igneous province (SW China): evidence for contrasting magmatic conditions of A-type granitoids
TheEmeishan large igneous province contains a diverse assemblage of igneous rocks includingmildly peralkaline granitic rocks ofA-type affinity. The granitic rocks from the Panzhihua, Baima andTaihe plutons are temporally, spatially and chemically associatedwith layeredmafic-ultramafic intrusions. Electronmicroprobe analyses of themajor and accessoryminerals along with major and trace element da...
متن کاملژئوشیمی، سنگزایی و کانیزایی سنگهای نفوذی نامن، جنوب غربی پهنهی سبزوار
Namen pluton is located in the SW of Sabzevar Zone and is composed of three different phases include two granitoid units and a basic phase. Namen syeno-granites (SG unit) are high temperature magmas enriched in HFSE such as Ga, Nb, Ta and Zr; and classified as aluminous A-type granitoids. This magmatic phase has been generated by partial melting of felsic rocks. The main phase of Namen pluton (...
متن کاملPetrography and geochemistry of the Kahrizbeyg intrusion, southwest of Zanjan
The Kahrizbeyg pluton is located northwest of Iran in Central Iran zone. It is emplaced into the Cretaceous limestones in which contact metamorphism has happened. Meanwhile, rock fragments of this pluton are found in conglomerate units of Early Oligocene Lower Red Formation. Therefore, the relative age of pluton is between Cretaceous and Oligocene. The Kahrizbeyg pluton consists of granite and ...
