Weakly alkaline trachybasalt - rhyolite series from Teplá Highland, western Bohemia - geochemical constraints.
a comagmatic differentiation suite generated by medium-grade partial melting of mantle is typical for the WAS. Salic derivatives (rhyolite and trachyte) reveal anomalous-oxyhydroxide vein mineralisation. The presence of sulphur in ...

Thermomagnetic curves of selected phonolites and trachytes of the České středohoří Mts
Variability of the temperature dependance of magnetic susceptibility and crystalochemical properties of the Fe-Ti oxides have been investigated for 21 samples of trachytes and phonolites from the České středohoří Mts. It was confirmed that m...

The mechanism of flow and fabric development in mechanically anisotropic trachyte lava
Anisotropy of magnetic susceptibility (AMS) and Electron back-scattered diffraction (EBSD) of magnetite and sanidine fabrics throughout an eroded trachyte lava dome in Tertiary volcanic province of the NW Czech Republic revealed two fabric d...

Instrumental neutron and photon activation analysis in the geochemical study of phonolitic and trachytic rocks
More than 130 samples of Tertiary phonolitic, trachytic and trachyandesitic rocks, representing evolved members of strongly and weakly alkaline volcanic rock series of the Ohre (Eger) Rift in the Bohemian Massif, Czech Republic, were analyse...

The effect of diffusive re-equilibration time on trace element partitioning between alkali feldspar and trachytic melts
We present new experimental data on major and trace element partition coefficients between alkali feldspar and trachytic melt. Experiments were conducted at 500 MPa, 870-890 degrees C to investigate through short disequilibrium and ...

Geochemical characteristics and magmatic differentiation of phonolites and trachytic rocks from the České Středohoří Volcanic Complex, the Ohře Rift, Bohemian Massif
Trachyandesites, trachytes and phonolites represent the most evolved rock types within the České Středohoří Volcanic Complex (CSVC) in the Ohře/Eger Rift. The K?Ar ages of the suite range from ~33.8 to ~25.8 Ma. Major and trace element varia...

Phonolite and trachyte dykes on Huseň Hill in the Doupovské hory Mts.
A network of trachyte and phonolite dykes penetrating phlogopite-phyric hory Volcanic Complex. Trachytes and phonolites are rather scarcely exposed of trachyte to phonolite dykes penetrating inseveral directions (NNW-SSE, E...
