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...
neyshabour turquoise mine is located in northwest of neyshabour, southern quchan volcanic belt. eocene andesite and dacite forming as lava and pyroclastic rocks cover most of the area. subvolcanic diorite to syenite porphyry (granitoids of magnetite series) intruded the volcanic rocks. both volcanic and subvolcanic rocks are highly altered. four types of alteration are recognized including: sil...
Abstract The transformation of technogenic Cu and Zn compounds in technogenically transformed soils (Spolic Technosols) with high very concentrations metals formed at the site a natural tailings pond floodplain Seversky Donets River, main tributary Don River (Rostov oblast, Russia) has been studied. Technosols are compared to an unpolluted meadow-chernozemic soil (Fluvisol) outside impact zone....
Abstract The Girilambone copper deposit of New South Wales, Australia, serves as an end-member model for development a classic oxidation-zone profile in environment virtually free both the effects active tectonics and significant fluctuation local water table. oxidation zone other deposits may be interpreted history recently tectonics, palaeoclimate, water-table stability by comparison to depos...
cheshmeh-konan area is located ~15 km northwest of tasuj, east-azarbaidjan province. the most important lithologic units of the area are red sandstones, green-gray sandstones, shale, and marl (miocene). based on field evidence and petrographical investigations, the host sediments were deposited in a peritidal setting associated with a sabkha-type environment. copper mineralization in the area o...
principal skarn deposits along the northern margin of the ahar batholith from west to east include mazraeh, vine and gowdoul skarn deposits. among these skarn deposits, the mazraeh cu-fe skarn deposit is the most typical skarn deposit in the nw iran. this skarn deposit is located 5 km. north of mazraeh village and 20 km north of ahar town. the origin and development of the skarn can be related ...
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...
Principal Skarn deposits along the northern margin of the Ahar batholith from west to east include Mazraeh, Vine and Gowdoul skarn deposits. Among these skarn deposits, the Mazraeh Cu-Fe Skarn deposit is the most typical skarn deposit in the NW Iran. This skarn deposit is located 5 km. north of Mazraeh village and 20 km north of Ahar town. The origin and development of the skarn can be related ...
Cheshmeh Gaz (Nasim) copper deposit is located in northwest of Bardaskan, Khorasan Razavi province. Geology of the area is consist of andesite, basalt, nummulitic limestone, and marl with gypsum intercalations Eocene in age, Pliocene conglomerate, and Quaternary sediments. Mineralization has been formed in andesites and contact between andesitic units and limestone as stratabound with dissemina...
Gazu copper deposit is located in the boundary of Tabas and Lut block, 65km southeast of Tabas and 15km southwest of Deyhouk. The dominant lithology in the area consists of Shotori dolomite and limestone and Shemshak shale and sandstone. Intrusive rocks with intermediate composition are widespread and numerous in the area. They consist of diorite, monzonite, and quartz monzonite to granite. Mi...
