Abstract At the Exótica deposit, south of giant porphyry copper deposit Chuquicamata (Atacama Desert, Chile), Cu-rich groundwater seeped out at several locations in open pit (Mina Sur) during sampling 2009–2011. their outflows, these solutions formed blueish and greenish copper-bearing gel-like precipitates. These gels contained atacamite sulfate hydroxides such as devilline, spangolite, posnja...
Research subject. The orogenic marginal-continental and collisional volcanic-plutonic belts, the zonality of magmatism metallogeny within them, as well relationship endogenous with magmatic geodynamics belt formation. Materials methods include long-term studies Devonian Upper-Paleozoic belts Kazakhstan Cretaceous-Paleogenic Sikhote-Alin; an analysis alterations in material parameters magmatites...
In this work, we focus on investigating the Quickbird and Landsat-8 datasets for mapping hydrothermal and gossans alterations in reconnaissance porphyry copper mineralization in the Babbiduyeh area. This area is situated in the Central Iranian Volcano-sedimentary Complex, where large copper deposits like Sarcheshmeh as well as numerous occurrences of copper exist. The alteration zones are discr...
The potassium silicate (K-silicate) alteration zone is the main ore contributor in porphyry copper deposits worldwide. Knowledge of element behaviors and mineralization processes essential for an improved understanding mineralization, but they are still not well understood. In this study, we reacted synthetic Cl-rich fluids, containing K, Na, Cu, Mo, Zn, etc., with andesite a complex experiment...
In this study, the zonality method has been used to separate geochemical anomalies and calculate erosional levels in regional scale for porphyry-Cu deposit, Abrisham-Rud (Semnan province, East of Iran). maps multiplicative haloes, co-existence both supra-ore elements sub-ore local maxima implied blind mineralization northwest study area. Moreover, considering calculated indices two previously p...
Primary tin deposits usually contain little or no copper due to the distinct geochemistry of Sn and Cu. However, examples copper-rich in many provinces around world are also well known. The genesis remains controversial. Maodeng Sn-Cu polymetallic, a typical Cu-rich deposit southern Great Xing’an Range (SGXR) Northeast China, offers an excellent opportunity reveal coupled copper-tin deposits. o...
One of the silver resources is Cu-Mo porphyry deposits, producing silver as by product. For this research, the results of analysis of 607 lithogeochemical samples for W, Zn, Ag, As, Ba, Co, Cu, Mo, Pb, Sb, Sn, Sr, Bi elements were used to investigate geochemical behavior of silver element in Hararan area which is located in the southeast of Iran and consists of copper mineralization seems to b...
