Time-scale of deformation and intertectonic phases revealed by P?T?D?t relationships in the orogenic middle crust of the Orlica-Snieznik Dome, Polish/Czech Central Sudetes

Popis výsledku v původním jazyce

A section of the orogenic middle crust (Orlica-Snieznik Dome) was examined to constrain the duration and significance of deformation (D) and intertectonic (I) phases. Three deformation events produced an initial subhorizontal foliation S1, a subverticalfoliation S2 and a late subhorizontal cleavage S3 (D3). The synform was intruded by pre-, syn- and post-D2 granitoid sheets. The P?T path, obtained by modelling the stability of parageneses and garnet zoning, shows near-isobaric heating from ~4 kbar/485°C to ~4.75 kbar/575 °C during I1?2. This was followed by a progression to 4?5 kbar/580?625 °C and a pressure decrease to 3?4 kbar during D2. Pressure decrease below 3 kbar is ascribed to I2?3, whereas cooling below ~500 °C occurred during D3. In the dated mica schist sample, garnet rims show strong Lu enrichment, oscillatory Lu zoning and a slight Ca increase, related to allanite breakdown coeval with staurolite appearance. As Lu-rich garnet rims dominate the Lu?Hf budget, the 344+/-3 M
