The Upper Cretaceous Sannae-Eonyang granite crystallized approximately 73 Ma and hosted the Sannae W-Mo deposit in west Eonyang amethyst east. contained textural zones of miarolitic cavities unidirectional solidification texture (UST) quartz. UST rock sampled mine consisted (1) early cavity-bearing aplitic granite, (2) co-crystallization feldspars quartz a granophyric (3) latest growth larger c...

introduction there is an iron mining complex called shahrak 60 km east of takab town, nw iran. the exploration in the shahrak deposit (general name for all iron deposits of the area) started in 1992 by foolad saba noor co. and continued in several periods until 2008. the shahrak deposit comprising 10 ore deposits including korkora-1, korkora-2, shahrak-1, shahrak-2, shahrak-3, cheshmeh, golezar...

The mineral system concept, which combines integrated information from all kinds of geological and geophysical studies, is a very useful approach to predict locate structures lithologies potentially associated with gold mineralization at scales (i.e., upscaling craton-to district-to camp-to deposit-scale). This demonstrated in this study where the Yaou deposit, located French Guiana within Rhya...

The high sulfidation epithermal gold deposit El Guanaco is located in the Palaeocene-Lower Eocene metallogenic belt Antofagasta Region, northern Chile, 215 km SE of city. characterized by a system sub-parallel ledges made vuggy silica and quartz enargite veins. In Cachinalito sector, on north western side ore deposit, has discontinuous linear morphology, with general ENE-OSO orientation, consis...

The Wulonggou Gold Field is one of the giant gold fields in East Kunlun Orogenic Belt, northwestern China. Previous studies mainly focused on elementary mineral isotopic studies, fluid inclusions, and geological features Field. In this study, we report some research precise age specific ore-forming process WGF: hydrothermal monazite U–Pb ages; way precipitation; composition, evolution, source f...

• Gold mineralization occurred in the subduction stage of Early Paleozoic Proto-Tethys ocean, and its age is limited between 454 Ma 439 Ma. H-O-S-Pb-Hf isotopes indicate a magmatic-hydrothermal source, closely related to monzogranites. The Heihaibei gold deposit may instead be classified as granitic intrusion-related deposit. newly discovered southern part Eastern Kunlun Orogenic Belt. Its most...

The Cabaçal deposit is located in SW Amazonian Craton, Mato Grosso State, Brazil, with important Au-Zn-Cu mineralization. ore hosted by the Alto Jauru orogenic rocks (1.79-1.74 Ga) comprised of felsic volcanic and volcanoclastic mineralizations occur as bands concordant mylonitic foliation, breccias, quartz-carbonate veins rock-disseminated, polymetallic comprises chalcopyrite, pyrite, marcasit...

introduction the mahour exploration area is a polymetallic system containing copper, zinc and silver. the mineralization can be seen in two forms of veins and disseminations. this area is structurally within the lut block, west of deh-salm village. recent exploration work and studies carried out by geologists on this volcanic-plutonic area of lut demonstate its importance indicating new reserve...

In 1975, Social Security beneficiaries were given the option of having their monthly benefit payments sent directly to their banks through an electronic funds transfer system. Since then, beneficiaries have been enrolling in this program in rapidly increasing numbers. At the end of 1976, fewer than 5 million beneficiaries--14 percent of the total--were enrolled in the program. By the end of 198...
