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...

Post-mineralization activities may cause difficulties in the process of ore modeling in porphyry deposits. Sungun, NW Iran, is one of the porphyry copper deposits, in which dyke intrusions have made ore modeling more complicated than expected. Among different kinds of dykes, two types were chosen and the consequent geostatistical analyses were applied on. In this study, simple directional vario...
