Five main apatite deposits from the Moroccan Central High-Atlas —including Anemzi, Tirrhist-Inouzane, Tassent, Ait-Daoud-Toumliline and Tasraft— have been investigated through integrated field, petrographic, mineralogical, geochemical studies. The ore occurs as veins, few mm to several cm thick, spatially associated with syenite-quartz monzonite (dominant) monzodiorite-gabbrodiorite bodies empl...
The Vathi porphyry Cu-Au ± Mo mineralization is located in the Serbo-Macedonian metallogenic province of Western Tethyan Metallogenic Belt. It mainly hosted by a latite and genetically associated with quartz monzonite intrusion, which intruded basement rocks Vertiskos Unit latite, 18 to 17 Ma ago. A phreatic breccia crosscuts latite. was affected potassic alteration, whereas subjected local pro...
This study provides a global assessment of the abundance major oxides in deep continental crust. The combination geochemistry and seismology better constrains composition middle lower crust than either discipline can achieve alone. inaccessible nature (typically >15 km) forces reliance on analog samples modeling results to interpret its bulk composition, evolution, physical properties. A common...
The area of study is located 120 Km north-east of Shahrood city. In terms of structure and geological classification, this area is located in the northern part of central Iran zone. Granitoids of Troud ranging from monzonite to granite. The main minerals of granitoids are quartz, plagioclase, and orthose. The accessory minerals are biotite, hornblende, sphene, and opaque minerals. Various textu...
The Nabar plutonic rocks is located in the northwest of Isfahan and in the Urumieh-Dokhtar magmatic belt. Based on the petrologic studies, the Nabar complex is composed of gabbro, gabbro-diorite, diorite, quartz diorite, tonalite and quartz monzonite. Mineral chemistry shows that pyroxenes are Na-poor in composition and are classified as clinopyroxenes and orthopyroxenes which are diopside and ...
Incheh granitoid intrusion is located east of Herris, East-Azerbaijan Province. It intruded into the older rock units including Eocene volcanic – volcaniclastics. Compositionally, this intrusion ranges from diorite-quartz diorite to monzonite. Chemical composition of its major minerals such as feldspars, amphibole and clinopyroxene analyzed using electron probe micro-analyzer (EPMA) for thermob...
Eocene- Oligocene volcanic and subvolcanic bodies of Masjed-Daghi Located in 35 km East of Jolfa close of Aras River. On the base of structural geology the study area is a part of the West Alborz-Azarbayejan zone. Volcanic rocks are rhyolite, dacite to trachyandesite and subvolcanic rocks are porphyritic monzonite to diorite. The Formation of these rocks related to subduction zone in an active...
Hassan Abad Au-Sb prospect area is located in north of Khorasan Razavi Province about 45 km souht of Neyshabour. Volcanic rocks (rhyolite, rhyodacite, trachyandesite and andesitic-basalt) and sub-volcanic intrusive (Eocene-Oligocene) such as biotite diorite porphyry, biotite hornblende diorite porphyry, hornblende monzonite porphyry, biotite micogranite, micogranodiorite, and granodiorite were ...
The Maherabad gold-rich porphyry copper prospect area is located in the eastern part of Lut block, east of Iran. This is the first porphyry Cu-Au prospecting area which is discovered in eastern Iran. Fifteen mineralization-related intrusive rocks range (Middle Eocene 39 Ma) in composition from diorite to monzonite have been distinguished. Monzonitic porphyries had major role in Cu-Au mineraliza...
Magmatic zircon tends to present characteristic trends in trace element compositions response magma petrogenesis and metallogenesis, such that may provide a window into melt evolution not accessible by whole rock chemistry. The Yangla large Cu deposit is located the central part of Jinshajiang Suture Zone, southwest China, constrained between Faults. In this study, elements hafnium isotopic zir...
