Geochemistry of the Rare Earth elements in spilites from the oceanic and continental crust

Autor: Albert Günter Herrmann, Mark J. Potts, Doris Knake

Publikováno v: Contributions to Mineralogy and Petrology. 44:1-16

Analytical data including major elements, the Rare Earths, Ni, Cu, Zn, Rb, and Sr are presented for twenty-three spilites from the Mid-Atlantic Ridge, the Hercynian part of the Variscan geosyncline in Germany, and several localities in Switzerland. L

Major and trace element compositional data are reported for nine mafic and ultramafic rock samples from the Barberton greenstone belt. Rocks from this province are among the oldest fragments of the Earth's crust (∼3.5 b.y.). The data are consistent

Coulometrisches Verfahren zur Bestimmung von Gesamt-, Carbonat- und Nichtcarbonat-Kohlenstoff in magmatischen, metamorphen und sediment�ren Gesteinen

Autor: Albert Günter Herrmann, Doris Knake

Publikováno v: Fresenius' Zeitschrift f�r Analytische Chemie. 266:196-201

Fur die Bestimmung von Gesamt-, Carbonat- und Nichtcarbonat-Kohlenstoff in magmatischen, metamorphen und sedimentaren Gesteinen (auch bei hoheren Anteilen an organischem C) ist ein Verfahren nach dem Prinzip der coulometrischen Titration geeignet. De

Geochemistry of modern seawater and brines from salt pans: Main components and bromine distribution

Autor: Jiirgen Schneider, Doris Knake, Heide Peters, Albert Gfinter Herrmann

Publikováno v: Contributions to Mineralogy and Petrology. 40:1-24

Seawater at different stages of evaporation from the salt works of Secovlje near Portorož (Yugoslavia) was analyzed geochemically. The seawater there passes through 20 stages of concentration until the first halite crystallizes. All important parame
