Petrology of a composite dike with biotite granite porphyry and hornblende quartz diorite porphyry at Shirotori, Kagawa, Japan.

u-pb zircon geochronology, rb-sr and sm-nd isotope geochemistry, and petrogenesis of granitiod rocks at kaje prospecting area, northwest ferdows: evidence for upper cretaceous magmatism in lut block

granitoid rocks of kaje area, northwest ferdows, with the composition of diorite, monzodiorite, monzonite, monzogranite, syenogranite and granite, with calk-alkaline and high potassium affinities, have trace and rare earth element geochemical characteristics similar to those from subduction zones, belonging to i-type granitoid rocks. most of these rocks are oxidized (magnetite series), while on...

بررسی‌های دورسنجی، زمین‌شناسی، دگرسانی، کانی‌سازی و ژئوشیمیایی در گستره‌ی پی‌جوئی مس- طلا بالازرد، غرب نهبندان

Balazard area is located in west of Nehbandan in the center of Lut Block. Eocene andesite and rhyolite cover most of the area. Subvolcanic rocks such as quartz monzodiorite porphyry, biotite quartz diorite porphyry, pyroxene hornblende diorite porphyry, hornblende pyroxene quartz diorite porphyry and hornblende diorite porphyry intruded the volcanic rocks. Evidence such as disseminated sulfide ...

سنگ‌شناسی، کانی‌شناسی منطقه‌های دگرسانی و پی‌جویی‌های ژئوشیمیایی در منطقه‌ی جنوب‌باختری سرخ کوه، شرق ایران

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...

Petrography and geochemistry of magmatic rocks in north of Kalate Shab area (East of Sarbisheh), Eastern Iran

The study area is located about 105 kilometers east of Sarbisheh in Southern Khorasan and in the Sistan suture zone. The magmatic rocks of this area are exposed as intrusive and sub volcanice including diorite, quartz diorite, porphyry quartz diorite and porphyry diorite with Oligocene- Miocene age. These rocks have granular, porphyry with fine- grained matrix, ophitic, intergranular and glomer...
