introduction the study area is located in the central part of the khaf- kashmar- bardaskan volcano-plotunic belt (briefly kkbb). several iocg deposits such as tanourjeh au-bearing magnetite deposit and kuh-e-zar specularite-rich au deposit have been explored in kkbb. geology, alteration, mineralization, geochemistry and fluid inclusion results in kashmar suggest the iocg type au-bearing magneti...

Mineralization at the supergiant Cu-U-Au-Ag Olympic Dam deposit (South Australia), ‘uranium endmember’ of iron-oxide copper–gold (IOCG) spectrum ore deposits, is hosted in a breccia complex developed entirely within granite 1.59 Ga Hiltaba Suite (Gawler Craton). Earlier studies suggested brecciation and mineralization occurred magmatically-driven hydrothermal system Ga, with critical role for m...

The mid-Proterozoic (ca. 1850–850 Ma) is a peculiar period of Earth history in many respects: ophiolites and passive margins this age are rare, whereas anorthosite A-type granite suites abundant; metamorphic rocks typically record high thermobaric (temperature/pressure) ratios, ultrahigh pressure (UHP) rare; the abundance economic mineral deposits features rare porphyry Cu-Au abundant Ni-Cu Fe-...

The Kiruna mining district, Sweden, known for the type locality of Kiruna-type iron oxide–apatite (IOA) deposits, also hosts several Cu-mineralized deposits including oxide–copper–gold (IOCG), exhalative stratiform Cu-(Fe-Zn), and structurally controlled to stratabound Cu ± Au. However relationship between IOA Cu-systems has not been contextualized within regional tectonic evolution. A broader ...

The Southeast Missouri Iron Metallogenic Province in the Midcontinent USA contains seven major and several minor IOA/IOCG-type deposits a series of shallow vein-type deposits/prospects, all which are spatially temporally associated with early Mesoproterozoic (1500–1440 Ma) magmatism St. Francois Mountains terrane. One is Shepherd Mountain deposit, consists two northeast-trending ore veins domin...
