Red ochres form in the oxidised, weathered portions of iron-rich mineral deposits, especially those associated with so-called volcanic massive sulfide (VMS) deposits where they are derived from the breakdown of minerals such as iron pyrite and chal-copyrite and also from the direct weathering of hematite, the... [Pg.320]

Most copper deposits are (/) porphyry deposits and vein replacement deposits, (2) strata-bound deposits in sedimentary rocks, (J) massive sulfide deposits in volcanic rocks, (4) magmatic segregates associated with nickel in mafic intmsives, or (5) native copper, typified by the lava-associated deposits of the Keweenaw Peninsula, Michigan. [Pg.193]

Metalliferous sediments are a common component of modern ocean-floor sedimentary sequences, recording halos of metal dispersion from seafloor hydro-thermal vent systems (Gurvich, 2006). Sulfidic black shales are also commonly present as intercalations in ancient subaqueous volcanic sequences, where each likely represents a significant hiatus in volcanic activity and deposition. These shale horizons form geophysical anomalies (conductors) that are routinely drilled during exploration for volcanogenic massive sulfide (VMS) base metal deposits. [Pg.19]

Syngenetic massive sulfides are largely concentrated along several prominent horizons corresponding to discrete breaks in volcanism, which are marked by the... [Pg.177]

Fig. 5. Zr/AbOs vs. Y/AI2O3 plot showing tholeiitic-transitional, transitional, and transitional-calc-alkaline nature of the volcanic rocks that host the Restigouche massive sulfide deposit. Zr/Y boundary ratios for the trends that divide the tholeiitiic-transitional and transitional-calc-alkaline fields are 4.5 and 7, respectively. Fig. 5.
