The sowthwest of Sorkh kuh prospecting area is located in 120 km SW of Birjand city, western Lut Block. Geology of this area comprising andesitic and basaltic volcanic rocks, which have intruded by intrusive rocks such as hornblende diorite, hornblende tonalite, and biotite monzonite caused extensively alteration and mineralization. Based on remote sensing, field survey, petrography, and XRD, m...

Fadiheh copper-gold prospect area in northwest of Torbat-e Heydariyeh in Khorasan Razavi Province is located in the central part of the Khaf-Kashmar-Bardaskan magmatic belt. This area includes outcrops of Eocene volcanic-pyroclastic units with felsicـintermediate nature. The lavas are andesite and latite, and pyroclastic units include rhyodacitic tuff, andesitic lithic tuff and ignimbrite. Intr...

West and south­west of Razan igneous rocks are located in the Hamedan Province in the Sanandaj- Sirjan zone, west Iran. According to petrography and chemical studies, these rock bodies are composed of diorite, gabbrodiorite, monzonite, quartz- monzonite, andesite and andesibasalt. The results of geochemical analysis show that these rocks belong to a cal- alkaline magma series. The geochemical c...

The Nokeh intrusion exposed in the northern Semnan area. The intrusion is composed of monzonite-quartz monzonite and granite-granodiorite and was intruded in the Eocene carbonaceous tuffs, where the country rocks converted to magnetite-skarn. Plagioclase, orthoclase, quartz, biotite, amphibole and clinopyroxene are the constituent minerals of Nokeh intrusion. The study rocks represent granular,...

Granitoidic bodies of the eastern Misho mountains (SW Marand – East Azerbaidjan) have intruded into Kahar Formation and mafic – ultramafic rocks of Misho mountains and has faulty contact with Triassic carbonate deposits. The composition of these bodies ranges from quartz monzonite to granite and alkali-granite and it is cut by porphyritic granitic and diabasic dykes. The main minerals of these ...

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 ...
