  abstract = {{G}ranitic pegmatites are exceptional igneous rocks and the possible role of an immiscibility process in their origin is strongly debated. {T}o investigate metal and metalloid behaviour in hydrous peraluminous systems (aluminium saturation index, {ASI} >1), we analysed 15 quartz-hosted primary melt and fluid inclusions from pegmatites in the {E}hrenfriedersdorf {C}omplex ({E}rzgebirge, {G}ermany) and 26 primary melt inclusions from leucogranites of the {E}hrenfriedersdorf district ({G}ermany), {K}ymi ({F}inland) and {E}rongo ({N}amibia) by femtosecond laser ablation inductively coupled plasma quadrupole mass spectrometry. {T}he results presented here for 32 elements provide evidence for metal and metalloid fractionation between two types of immiscible melts ({A} and {B}) and {N}a{C}l-{HC}l-rich brine in the pegmatite system. {N}o evidence for the boundary layer effect was observed in the 40-500 mu m size melt inclusions that were investigated. {T}he data on the {E}hrenfriedersdorf pegmatites allow quantification of the metal and metalloid partitioning between natural {N}a{C}l-rich brine and the two types of melt (e.g. {K}-{A}s(brine/type-{A},{B} melts) = 0.01-1.7; {K}-{S}b(brine/type-{A},{B} melts) = 10-285; {K}-{Z}n(brine/type-{A},{B} melts) >= 50; {K}-{P}b(brine/type-{A} melt) >= 50; {K}-{A}g(brine/type-{A} melt) = 46). {T}hese data are in accord with existing natural and experimental data on equilibrium fluid melt partitioning as well as spectroscopic data on the metal and metalloid complexation in hydrous aluminosilicate melts and {N}a{C}l-{HC}l-rich fluids.},
