Jarou deposit, with age of Middle Eocene –Oligocene, is located in 60 km to the southwest of Karaj and lies within magmatic rocks with felsic to basic composition. Host rock geochemical results have implied a calc-alkaline nature, magmatism related to an extensional back arc regime and lack of economic potential for igneous rocks. Petrographic and geochemical evidences of Cu minerals have shown...

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...

Remote sensing plays an important role in mineral exploration. One of its proven applications is extracting host-rock lithology and alteration zones that are related to porphyry copper deposits. An Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) was used to map the Baogutu porphyry deposit alteration area. A circular alteration mineral zoning pattern was clearly observed ...

We provide here information on the distribution of copper, zinc, lead, gold, silver, barium, arsenic, antimony, mercury, selenium and tellurium in the Moore and Monte Negro high-sulfidation epithermal deposits in the Pueblo Viejo district, Dominican Republic. Moore and Monte Negro are funnel-shaped zones of advanced argillic alteration and precious-metal mineralization which extend to depths of...

The fabrication of graphene devices can be challenging due to exposure to harsh chemicals and mechanical wear such as ultrasonication used for cleaning in photolithography and metal deposition. Common graphene processing methods often damage fragile graphene sheets and can ruin the device during fabrication. The authors report a facile method to overcome many of these challenges, which is speci...

This article describes the geology and industrial mineral potential of corundum, pyrophyllite and andaluite at the Empress deposit in the Taseko Lakes area (Figure 1). The Empress is a copper-goldmolybdenum porphyry deposit located 225 kilometres north of Vancouver and 50 kilometres northwest of Goldbridge and the Bralorne mining camp. Fine-grained corundum, in association with andalusite-pyrop...

Объемное цифровое моделирование тел полезных ископаемых в процессе добычи и эксплуатационной разведки все более активно внедряется практику работ горнодобывающих предприятий для оперативного планирования учета движения запасов. В то же время проходка разведочных скважин разных плоскостях разрабатываемого объема геологического пространства создает сложности увязке границ рудных межпрофильном про...
