Description:
This study addresses the polyphase
Miocene tectonic evolution in the
Maramures area (northern Romania) by combining field observations,
stratigraphic arguments and
fission-track analysis (Tischler et al.
in press). Fission-track analysis has
been carried out on basement samples from the Rodna horst, situated
in the East Carpathians (Bucovinvian
nappes). This area was affected by Cretaceous
medium- to low-grade metamorphism,
followed by post-collisional exhumation
and renewed moderate thermal
overprint due to the deposition of
Eocene to Early Miocene sediments.
Based on paleostress analyses of mesoscale
structures, three main tectonic
phases can be disdinguished in the
study area, all of which are postdate
the earliest Miocene (Aquitanian,
20.5 Ma). In late Early Miocene
(Burdigalian) the Pienide nappes, nonmetamorphic
flysch series, were emplaced
onto the Paleogene to Early
Miocene sedimentary cover of the Bucovinian
nappes...
