Role of halogens (especially, Cl) as well as slab-derived melts (adakites) and hydrous fluids in highly siderophile (PGE and Au) and chalcophile element mobility in subduction zones.

Role of mantle wedge, island-arc crust (arc plutonic complexes) and subducting slab in ore-formation processes.

Influence of oxygen and sulfur fugacity on metal behavior in magmatic arcs and collisional orogens

Magmatic arcs are enriched in some HSE (Pt, Pd, Au) in comparison with other tectonic settings with contributions from the mantle wedge, island-arc crust and saline (Cl-rich) slab-derived fluids.

Adakites (high Sr/Y slab or lower crust melts) and high-Nb basalts (products of adakite-mantle wedge interaction) carry large amounts of ore metals and are associated with giant metal deposits in subduction settings. Water content of adakite magmas along with abrupt changes in oxygen fugacity are main controlling factors in ore genesis in magmatic arcs.

Explosive volcanism and liquid immiscibility in metal-silicate systems plays important role in the formation of magmatic gold (with copper and silver) deposits.

Role of slab melting and adakite-mantle wedge hybridization in genesis of arc magmas.

Crystal fractionation of primitive picritic, basaltic and andesitic melts in magmatic plumbing systems (crustal magma chambers) in volcanic arcs.

Redox heterogeneity in subduction zones.

Slab melting and slab melt-peridotite interaction are important petrogenetic processes in volcanic arcs responsible for generation of adakites, high-Mg andesites and high-Nb basalts.

Presence of native metals and intermetallic compounds in subduction-related rocks and mantle xenoliths suggest small-scale redox heterogeneity in subduction zones.

Crustal magmatic plumbing systems play important role in arc petrogenesis.

Volcanic wine terroirs (Sicily, British Columbia, Pacific Northwest, California)

Mineralogical and geochemical peculiarities of sediments associated with principal wine-growing regions.

Volcanic and volcano-sedimentary (black shale) terroirs.

Role of siderophile (PGE, Au, Ag) and chalcophile (Zn, Pb, Cu, Sb, Bi, etc.) elements in wine characteristics and development of the geochemical wine terroir concept.

Paleozoic black shale on both sides of the Pyrenees, in Priorat (Spain) and Maury (France) contain native silver, zinc, platinum and as well as various intermetallic compounds of highly siderophile and chalcophile metals, as well as sulfides (framboidal pyrite, sphalerite, chalcopyrite), barite, zircon, baddeleyite and apatite.

Priorat black shale is enriched in Pd-group platinum-group elements (Pt, Pd and Rh) as well as gold (Au up to 1500 ppb in individual samples).

Mineralogical and geochemical data on black shale from both sides of the Pyrenees suggest existence of well-established, persistent geochemical characteristics (geochemical terroir) that may bear strong influence on aromatic and gustatory qualities of wine.
