Distribution of siderophile and chalcophile elements in serpentinites of the oceanic lithosphere as an insight into the magmatic and crustal evolution of mantle peridotites

Magmatic–Hydrothermal Transport of Metals at Arc Plutonic Roots: Insights from the Ildeus Mafic–Ultramafic Complex, Stanovoy Suture Zone (Russian Far East)

“…The abundance and distribution of W, Mo, Cu and their isotopes in igneous rocks have been previously successfully used to reconstruct fluid regimes and redox conditions facilitating metal cycling in the crust-mantle system at convergent plate boundaries [116][117][118][119][120][121][122][123]. Figure 20 summarizes the distribution of siderophile (W, Mo) and chalcophile (Cu, Zn, As, Ag, Cd, Hg, Pb, Bi) elements in plutonic and metasomatic rocks from the Ildeus complex along with the later-stage felsic dikes.…”

“…St. Helens, Cascades elements in magmatic and metasomatic rocks from the Ildeus mafic-ultramafic complex (A-E) and modern lavas from volcanic arcs and oceanic islands (F). Data for comparison: variably serpentinized oceanic peridotites (Ag, As, Pb, Cd, Cu and Zn from [120]; Hg and Bi from [121]; Mo from [122]; W from [123]); supra-subduction zone (SSZ) peridotite, arc websterite and arc gabbro from [124]; pelagic clay sediment [98]; hypothetical hydrothermal fluid (Zn, Pb, W from [125]; Mo, Cu, As from [126]; Hg from [127]; Ag from [128]); oceanic basalt glasses from the Kilauea Iki lava lake [129]; arc volcanic rocks from the Andes [130], Masaya volcano, Nicaragua [116], Mt. St. Helens, Cascades [116]; Alaid volcano, Kuriles [116], Tolbachik volcano, Kamchatka [116], Setouchi high-Mg andesite (HMA) from SW Japan [119].…”
