This paper addresses the application of integrated chargeability and resistivity method and grade data in modeling and evaluation of copper deposits. We argue that the relationship between IP, Rs and grade data may be used for modeling and reserve estimation and tested this argument for Sarbisheh copper deposit that is located in eastern Iran. Geology and mineralization situation of Sarbisheh d...

Resources/reserves classification is crucial for block model creation utilised in mine planning and feasibility study. Selection of estimation methods is an essential part of mineral exploration and mining activities. In other word, resources classification is an issue for mining companies, investors, financial institutions and authorities, but it remains subject to some confusion. The aim of t...

Tungsten carbide particles reinforced metal matrix composite (MMC) coatings can significantly improve surface wear resistance owing to their increased hardness. However, the presence of macro- and micro-residual stresses in MMC have detrimental effects, such as reducing service life. In this study, neutron diffraction was used determine residual spherical fused tungsten (sFTC) Cu deposits after...

Abstract Most known porphyry Cu deposits formed in the Phanerozoic and are exclusively associated with moderately oxidized, sulfur-rich, hydrous arc-related magmas derived from partial melting of asthenospheric mantle metasomatized by slab-derived fluids. Yet, whether similar metallogenic processes also operated Precambrian remains obscure. Here we address issue investigating origin, f O 2 , S ...

The Qin-Hang Metallogenic Belt (QHMB), an important metallogenic belt in South China, hosts Cu and W–Sn polymetallic deposits. Tongshanling ore field the QHMB is characterized by coexistence of Cu- W-bearing deposits, which are related to granodiorite granite porphyry. This study examined whole-rock geochemistry, geochronology, Sr–Nd–Hf isotopes determine genetic relationship between diverse or...

The distribution of some heavy metals, namely Cd, Pb, Zn, Fe, Cu, Cr and Mn in epipellic sediments of Igbede, Ojo and Ojora rivers of Lagos was studied weekly in the early summer (November) of 2003. The levels of selected trace metals were determined using Atomic Absorption Spectrophotometer (UNICAM 969 AAS SOLAR). Trends in heavy metal burdens in the sediments revealed weekly variations in all...

Due to rapid industrialization and urbanization lead atmospheric deposition of heavy metals and dust load to become a global problem. We investigated the deposition of dust and heavy metals (Pb, Cd, Ni, Zn, Mn and Cu) at selected urban and sub-urban sites of Varanasi, India. Dustfall samples from different sampling location were collected and selected heavy metals viz. Pb, Cd, Cr, Ni, Zn, Mn an...

The Pellapahk Cu-Mo and Oleninskoe Au-Ag deposits in the western segment of Russian Arctic Kolmozero–Voronya greenstone belt are considered two parts an Archean (2.83–2.82 Ga) porphyry-epithermal system, probably oldest one defined Fennoscandian Shield. Formation deposit at epithermal stage system is indicated by spatial genetic relationships with sills granite porphyry, geochemical association...
