Thermochronological evidence for Mio‐Pliocene late orogenic extension in the north‐eastern Albanides (Albania)

New apatite and zircon (U–Th)/He and apatite fission-track (FT) data allow constraining the timing of Miocene–Pliocene extensional exhumation that affected the central part of the Dinarides-Albanides-Hellenides orogen. Apatite (U–Th)/He ages in the northern and western Internal Albanides range from 57 to 17 Ma, contrasting to younger ages of 5.2–9.3 Ma in the eastern Internal Albanides. Eastward younging is also reflected in zircon (U–Th)/He ages varying from 101 Ma in the north-western Internal Albanides to 19–50 Ma in the east, as well as in recently published apatite FT ages. Thermal history predictions with the new data point to a phase of rapid exhumation of the eastern Internal Albanides around 6–4 Ma, while the western Internal Albanides record slower continuous exhumation since the Eocene. This asymmetric exhumation pattern is most likely linked to extensional reactivation of NE–SW-trending thrusts east of the Mirdita zone and within the Korabi zone of the eastern Internal Albanides.
