The Rangraz area is located about 20 km north of Saveh, which is situated in the central part of Uromieh–Dokhtar magmatic arc. The exposed rocks in the study area consist of a volcanic and volcanoclastic subvolcanic dikes and quartz monzodiorite intrusions. Mineralization in this area is mostly related to the silicic, argillic and chloritization alteration assemblages. The Rangraz area consists...
Abstract Important fault zone processes can be discerned from the characterization of fracture damage and chemical transformations associated with active seismic sources. To characterize 2010 M7.2?El Mayor-Cucapah rupture zone, continuous samples core 23 damaged rock were collected perpendicular to strike Borrego fault. Samples analyzed for clay mineralogy, bulk geochemistry, grain density whic...
Methods for extracting mineralized alteration information using remote sensing images have recently become both efficient and cost-effective. Technology involving the extraction of based on multi-spectral data has been widely practiced effectively verified. In recent years, research fine mineral methods hyperspectral also rapidly developing. The Yulong copper belt is a porphyry located in China...
With the development of hyperspectral technology, it has become possible to classify alteration zones using data. Since various altered rocks are comprehensive manifestations mineral assemblages, their spectra highly similar, which greatly increases difficulty distinguishing among them. In this study, a Semi-Supervised Adversarial Autoencoder (SSAAE) was proposed zones, drill core data collecte...
Kariro Pb prospect area, which is located in northwest of Boshruyeh, occurs as vein-veinlets, open space filling, and cement of fault breccia in Middle Jurassic metamorphosed shale (slate) unit of Baghamshah Formation. Mineralization zones contain dolomite (70-85%) and galena (0.5-2.5%) with small amounts of pyrite, quartz, and calcite. Dolomitization and silicification of host rock are the mos...
MA-II area is one of the most important parts of Cu-Au porphyry mineralization at Maherabad prospect area. Subvolcanic intermediate intrusive rocks (Upper Eocene), monzonite to diorite in compositions, intruded telescopically and are mostly altered. Monzonitic porphyries had major role in mineralization. These intrusive rocks are highly altered, have dense stockwork veinlets, and show highest g...
The Haft Sandogh alunite deposit is located in the northwest of Takestan (about 60 Km west of Qazvin), and is a part of large Takand alunite deposit. Mineralogical and field study reveal that there is a zonation in the alteration zones of the Haft Sandogh deposit and surrounding area including silica zone in the central part, and quartz-alunite (quartz alunite), kaolinite and propylitic formed ...
the arghash area is located 45 km to southwest of neyshabour. the subvolcanic rocks in the area consist of biotite hornblende quartz monzodiorite porphyry, hornblende biotite quartz monzodiorite porphyry, hornblende monzonite porphyry, biotite hornblende monzonite porphyry, monzodiorite porphyry and biotite quartz monzodiorite porphyry units. the volcanic rocks consist of hornblende biotite dac...
introduction the garmab copper deposit is located northeast of qaen (south khorasan province) in the1:100,000 scale map of abiz in the eastern tectonic zone of iran. it is hosted by late paleocene-eocene lava flows consisting mainly of andesite, trachy andesite, andesite-basalt and basalt lavas, as well as pyroclastic rocks, including tuffs and ignimbrites. the lut block has undergone intense m...
