Indium (In) is commonly hosted in Sn-rich deposits but rarely reported in Sn-poor deposits. However, an In-rich and Sn-poor skarn deposit, the Qibaoshan Cu-Zn-Pb deposit, has been identified in south China. Geochemical analyses were undertaken on 23 samples representing the following mineral assemblages: sphalerite-pyrite, pyrite-chalcopyrite, pyrite-sphalerite-galena-chalcopyrite, pyrite, magn...

Porphyry Cu and epithermal deposits are spatially and temporally related to specific volcanic and plutonic rocks emplaced during the formation of long-lived magmatic arcs formed along convergent plate boundaries (e.g., Sillitoe, 1972; Sutherland Brown, 1976; Titley, 1982; Sawkins, 1990; Bissig et al., 2003). Recognizing the presence, types of deposits, and age of the mineralized volcanoplutonic...

Abstract Porphyry copper deposits, the principal source of and molybdenum, form at convergent margins. Copper is precipitated from fluids associated with cooling magmas that have formed in mantle evolved mid- to lower crustal levels, before rising toward surface where they saturate exsolve an aqueous fluid copper. Despite advances understanding their formation, there are still underexplored asp...

Acid-base accounting (ABA) is intended to estimate the quantities of minerals potentially capable of generating and neutralizing acid using chemical procedures. The neutralization potential (NP) component of ABA is more complex than acid potential (AP) because the minerals quantified in the analytical result may or may not contribute significantly to acid neutralization under field conditions. ...

Fe isotopes have been applied to the petrogenesis of ore deposits. However, behavior iron in mineralization porphyry-skarn deposits is still poorly understood. In this study, we report mineral separations (magnetite, pyrite, chalcopyrite and pyrrhotite) from two different skarn deposits, i.e., Tonglvshan Cu-Fe deposit developed an oxidized hydrothermal system Anqing Cu a reduced system. both ca...

introduction the garmab copper deposit is located northeast of qaen (south khorasan province) in the1:100,000 scale map of abiz in the eastern tectonic zone of iran. it is hosted by late paleocene-eocene lava flows consisting mainly of andesite, trachy andesite, andesite-basalt and basalt lavas, as well as pyroclastic rocks, including tuffs and ignimbrites. the lut block has undergone intense m...

The Sungun porphyry copper deposit is located in northwestern Iran and is associated with diorite/granodiorite to quartz-monzonite of Miocene age, which intruded Eocene volcanosedimentary and Cretaceous carbonate rocks. Copper mineralization was accompanied by both potassic and phyllic alteration. Three main mineralization related alteration episodes (potassic, transition, and phyllic alteratio...

The uniaxial compressive strength (UCS) of intact rocks is an important geotechnical parameter required for designing geotechnical and mining engineering projects. Obtaining accurate estimates of the rock mass UCS parameter throughout a 3D geological model of the deposit is vital for determining optimum rock slope stability, designing new exploratory and blast boreholes, mine planning, optimizi...
