Recent Advances in Porphyry Base Metal Deposit Researchated with hypabyssal epizonal plutons. The .-type affinity porphyry copper-molybdenum series is first established as petrogenically distinct from deposits associated with S-type, generally 2-mica granites, the porphyry tin — tin granite — uranium granite suite. Then five specific areas of advance in

The Geochemical Behaviour of Copper and Molybdenum in Ore-Forming Processesization is closely associated with the hydrothermal-metasomatic associations. The probable values of the physicochemical parameters of copper- and molybdenum-bearing hydrothermal solutions are estimated on the basis of calculations and experimental data. The problem of the types of copper and molybd

Space-Time Distribution, Crustal Setting and Cu/Mo Ratios of Central Andean Porphyry Copper Depositsnable to four longitudinal sub-belts of Meso-Cenozoic age, which become progressively younger from Late Cretaceous in the west, through Paleocene and Late Eocene-Early Oligocene, to Middle-Late Miocene in the east. A fifth, Late Carboni-ferous-Early Permian sub-belt is overprinted by the Middle-Late

Sequences of troctolite and anorthosite form cyclic units in which the crystallization of plagioclase was followed by precipitation of plagioclase plus olivine. Chemical variations associated with

Partial melting and devolatilization of country rocks are important processes in the generation of many Cu—Ni deposits associated with mafic igneous rocks. Sulfur isotopes provide a means of evaluating the possibility of extraneous sulfur addition to a melt. Variability

Williamson and ore distribution: (1) stratiform, massive-matrix-disseminated sulfides hosted by cumulate komatiite lava flows (lava conduits), or strata-bound, coarse disseminated sulfides hosted by cumulate komatiite bodies near volcanic vents, and (2) strata-bound, finely disseminated sulfides and more rest
