dc.description.abstract | The Tatra granitoid pluton (Central Western
Carpathians, Poland/Slovakia) is an example of composite
polygenetic intrusion, comprising many magmatic pulses
varying compositionally from diorite to granite. The U–
Pb LA-MC-ICP-MS zircon dating of successive magma
batches indicates the presence of magmatic episodes at 370–
368, 365, 360, 355 and 350–340 Ma, all together covering a
time span of 30 Ma of magmatic activity. The partial resorption
and recycling of former granitoid material (“petrological
cannibalism”) was a result of the incremental growth
of the pluton and temperature in the range of 750–850 °C.
The long-lasting granitoid magmatism was connected to
the prolonged subduction of oceanic crust and collision of
the Proto-Carpathian Terrane with a volcanic arc and finally
with Laurussia, closing the Rheic Ocean. The differences in
granitoid composition are the results of different depths of
crustal melting. More felsic magmas were generated in the
outer zone of the volcanic arc, whilst more mafic magmas
were formed in the inner part of the supra-subduction zone.
The source rocks of the granitoid magmas covered the compositional
range of metapelite–amphibolite and were from
both lower and upper crust. The presence of the inherited
zircon cores suggests that the collision and granitoid magmatism
involved crust of Cadomian consolidation age (c.
530 and 518 Ma) forming the Proto-Carpathian Terrane, crust of Avalonian affinity (462, 426 Ma) and melted metasedimentary
rocks of volcanic arc provenance. | pl_PL |
