In order to explore probable blind mineralized zones of the Aliabad deposit, it is necessary to evaluate the element concentrations towards depth or margins of the deposit. Modelling primary geochemical haloes could be useful in this stage. Ore bodies at the Aliabad deposit are primarily controlled by structural features, which provide an opportunity to investigate the zonality in primary halos...
Anomaly recognition has always been a prominent subject in preliminary geochemical explorations. Among the regional geochemical data processing, there are a range of statistical and data mining techniques as well as different mapping methods, which serve as presentations of the outputs. The outlier’s values are of interest in the investigations where data are gathered under controlled condition...
This paper reports the results of a study magmatic rocks with Sn–W–Au–Ag mineralization from Kuranakh, Elikchan, and Istekh ore fields in Northern batholith belt north-eastern Verkhoyansk–Kolyma orogenic Eastern Russia. Using petrographic, mineralogical, geochemical, isotopic methods, we determined mineral compositions, petrochemistry, geochemistry rocks, P–T conditions their generation crystal...
The study area is located in North-East of Lut block, and in Basiran Geological Quadrangle Map (1:100000).Tertiary intrusive-subvolcanic rocks intruded Paleocene limestone and formed skarn and Iron mineralization. Petographic studies show that rocks are Hbl-diorite porphyry, Hbl-qtz- diorite porphyry, Px- diorite porphyry, Hbl-px- diorite porphyry, Hbl-diorite and Bt-diorite. These rocks are s...
Band-e-Ghichy copper deposit is located in the northern margin of the Central Iran structural zone, about 120 km south of Shahrood and 70 km south east of Torud. Copper mineralization occurred in the rock units including sandstone, conglomerate and siltstone with the Oligocene age. Mineralization has occurred in the form of stratiform (syngenetic), stratabound (epigenetic) and supergen (the sur...
The study area is located in Tertiary plutonic belt of Lut Block. Tertiary intrusive injection in Cretaceous limestone caused the formation of skarn in this region. Injection intrusive changes the texture and mineralogy of limestone and skarn or marble formed. A lens-shaped iron mineralization mainly occurred in the border of intrusions and calcareous unit. Petrological studies show that the w...
The Middle–Lower Yangtze River Metallogenic Belt is an important copper and iron polymetallic metallogenic belt in China. Today’s economic development inseparable from the support of metal mineral resources. With continuous exploitation shallow easily identifiable mines China, prospecting work deep hidden very important. Mineral prospectivity modeling (MPM) means to improve efficiency explorati...
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...
kalchouyeh area in southwest of naein is located in the urumieh-dokhtar volcano-plutonic belt. mineralization occurred mainly as disseminations and veinlets hosted by trachy-andesite and pyroxene andesites. for mineralogy, alteration, fluid inclusion and geochemical studies, the two major mineralized zones: a (larger vein) from the north-northwest and b (smaller vein) from the east-southeast of...
