Metamorphoseentwicklung im Kaokogürtel, NW-Namibia
… granulitfaziellen Metamorphose unterlagen. Für Metapelite lassen sich Metamorphosezonen mit aufsteigender Metamorphose von Ost nach West aushalten: Granat-Zone, Staurolith-Zone, Disthen-Zone, ky-sill-mu-Zone, sill-mu-Zone, sill-ksp-Zone, g-cd-sill-ksp-Zone. Mit Hilfe geothermobarometrischer und …

The effects of high temperature metamorphic and melting processes on granulite-facies rocks
… taken from a number of terranes show that in metapelites, melting and melt loss does not deplete U–Th concentrations, with overall terrane averages suggesting bulk heat production partitioning between melt and residuum is essentially 1:1. Modelling of HPE concentrations derived from …

LI, BE UND B IN MINERALEN METAPELITISCHER GESTEINE : FALLSTUDIEN AUF DER INSEL IKARIA, IM KÜNISCHEN GEBIRGE UND DEN SCHWEIZER ALPEN
… Hierfür wurden eine Reihe von krustalen Metapeliten und untergeordnet Kalksilikate/Amphibolite aus drei verschiedenen Regionen (Insel Ikaria, Ostägäis - Künisches Gebirge, BRD/Tschechische Republik - Campo Tencia, Schweiz) ausgewählt. Metapelite sind typische Krustengesteine, deren …

INTO THE STRUCTURE OF THE PERMIAN DEEP CONTINENTAL CRUST: A MULTISCALE APPROACH TO RECONSTRUCT MIGMATIZATION IN THE VALPELLINE SERIES (DENT BLANCHE TECTONIC SYSTEM, WESTERN ITALIAN ALPS)
… Alpine-age reworking. It shows migmatitic metapelite with different mineral assemblages (i.e., garnet-, cordierite- and orthopyroxene-bearing), amphibolite and marble, intruded by aplite and pegmatite. Melt production in metapelite and locally in amphibolite occurred during the development …

Petrography, geochemistry and stable isotope characteristics of the Navachab gold deposit, Namibia
… des Fluids werden tieferkrustale Equivalente der Metapelite der Damara-Sequenz, die eine prograde, amphibolit- bis granulitfazielle Metamorphose durchliefen, angenommen. Den für die Goldmineralisation erforderlichen Bestand an Metallen und Liganden (Fe, Mn, Mg, Cu, Bi, Au, Zn, S, Cl) könnte das …

LITHIUM ENRICHMENT IN ANATECTIC PEGMATITES: NEW INSIGHTS FROM THE THERMOMETAMORPHIC AUREOLE OF THE ADAMELLO BATHOLITH
… marking them as produced by direct anatexis of metapelites. They also show that they were formed by two melt batches of different trace element composition originated by differential in-source fractionation. Conversely, isotopic data characterizes the pluton-hosted pegmatites as mantle-derived …

Petrology, geochemistry, stable and radiogenetic isotopy of the Guelb Moghrein iron oxide copper gold cobalt deposit, Mauritania
… biotite-garnet-quartz schist is an intercalating metapelite. A suite of metavolcanic rocks of the Akjoujt Metabasalt unit including massive amphibolite lenses, biotite-actinolite- and chlorite schists dominate the deposit area. Textural and geochemical analyses indicate that the precursor volcanic …
