dc.description.abstract | In the Variscan Western Tatra granites hybridization
phenomena such as mixing and mingling can be observed
at the contact of mafic precursors of dioritic composition and
more felsic granitic host rocks. The textural evidence of
hybridization include: plagioclase–K-feldspar–sphene ocelli,
hornblende- and biotite-rimmed quartz ocelli, plagioclase
with Ca-rich spike zonation, inversely zoned K-feldspar
crystals, mafic clots, poikilitic plagioclase and quartz crystals,
mixed apatite morphologies, zoned K-feldspar phenocrysts.
The apparent pressure range of the magma hybridization
event was calculated at 6.1 kbar to 4.6 kbar, while the
temperature, calculated by independent methods, is in the
range of 810°C−770°C. U-Pb age data of the hybrid rocks
were obtained by in-situ LA-MC-ICP-MS analysis of zircon.
The oscillatory zoned zircon crystals yield a concordia age of
368±8 Ma (MSWD=1.1), interpreted as the age of magma
hybridization and timing of formation of the magmatic
precursors. It is the oldest Variscan magmatic event in that
part of the Tatra Mountains. | pl_PL |
