Transylvania Summary
1. Transylvania post-collisional history
- Intra-Albian (Mid-K, Austrian) Transylvanides
(over)thrusting in two steps - Post-Albian
extensional collapse - Intra-Turonian E-ward
Apuseni thrusting - post-Turonian, pre-top K
small grabens - Top-K (Laramian) inversion -
Eocene shortening
- Small normal faults during the Late Cretaceous.
In Transylvania two areas in particular hanging
wall of the Puini thrust (Internal Dacides,
Tisza) and Deleni structure. - Often smaller
Lower Miocene offsets - Symmetric small
grabens. - Age pre- Cretaceous Puini, i.e. pre-
intra-Turonian phase.
