Abstract Detailed mineralogical and textural studies, combined with sequential X-ray diffraction geochemical modeling, helped to solve the “copper pitch/wad” enigma in Exótica deposit located downstream of Chuquicamata porphyry copper deposit. Copper pitch wad are essentially chrysocolla co-precipitated Mn oxides, mainly birnessite, as well pseudo-amorphous oxide/oxyhydroxides. Linking mineralo...

Porphyry copper (Cu) systems occur along magmatic belts derived in subduction zones. Our current understanding of their formation is restricted to observations from the overriding plate, resulting a knowledge gap terms processes occurring convergence zones through time. An association between key tectonic and timing location porphyry Cu requires linking geological plate models. We connect evolu...

A bidimensional empirical mode decomposition (BEMD) program on a MATLAB platform was effectively used to handle gravity signals for the Tongshi gold field. This yielded a two-dimensional intrinsic mode function (IMF3) image that meticulously depicts the spatial distribution relationship between various gold deposits and the different geological units of the gold field. By combining the IMF3 ima...

The copper(II) complex of a novel rhodamine-azamacrocycle conjugate binds to the CXCR4 chemokine receptor and competes effectively against anti-CXCR4 monoclonal antibodies. The copper macrocycle unit adopts a trans-II configuration in the solid state.

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...

Pathological findings and liver and kidney analyses confirmed that cattle had died of chronic copper poisoning on a farm in the north-eastern Transvaal. This is the first known published record of chronic copper intoxication of cattle in southern Africa. An epidemiological study revealed that a source of copper was air pollution which could have arisen from a nearby copper smelting unit. Buffal...

The northwestern part of the Kerman Cenozoic magmatic arc (KCMA) contains many areas with porphyry copper mineralization. In this research, we used the advanced space-borne thermal emission and reflection radiometer (ASTER) and Enhanced Thematic Mapper plus (ETM+) images of this region to map the distribution of hydrothermally altered rocks, based on their mineral assemblages. The spectral meas...

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...
