“…The apatite grains of the Oligocene age cluster might have been derived from the contact metamorphic aureoles of the Periadriatic tonalite intrusions and/or from exhumed crystalline slabs of Oligocene cooling age situated along the Periadriatic lineament. Resetting and rapid exhumation from the apatite partial annealing zone in the Oligocene within the surroundings of the western Pannonian Basin occurred only along the Periadriatic lineament (Gieger and Hurford 1989;Hejl 1997;Läufer et al 1997;Sachsehofer et al 1998).…”

“…3) yield the youngest ages, around 32-28 MA and 18-5 MA. According to Läufer et al (1997), the 32-28 MA would correspond to emplacement of intrusives along the Gailtal Line (Laubscher 1983;Von Blankenburg and Davies 1995) in a context of dextral strike-slip transtensional movements (Frisch et al 1998). The youngest cluster of radiometric ages could reflect the Miocene exhumation phase of these units (Läufer et al 1997).…”

Thermal evolution of the Palaeozoic-Triassic sequences of the Carnic Alps has been characterized by b cell dimension and Kübler Index (illite ''crystallinity'') of K-white micas (KI), Á rkai Index (AI) of chlorites, clay mineral assemblages and conodont Colour Alteration Index (CAI). Data indicate at least two metamorphic events, Variscan and Alpine. In the older event high anchizonal conditions predominated although epizonal conditions were reached over wide areas. It was characterized by lowintermediate pressure facies. The thermal peak was mainly due to an extensional regime during the Bashkirian. A younger thermal overprint generated by Alpine orogeny was of lower grade, reaching high diagenetic-anchizonal conditions characterized by high-pressure facies. Inverted metamorphic patterns are associated with middle to late Miocene thrusting. Hydrothermal alteration in the northern part of the region can be linked with emplacement of Oligocene plutons and high heat flow along the Periadratic lineament.

Changing patterns of exhumation and denudation in front of an advancing crustal indenter, Tauern Window (Eastern Alps)

et al. 2017

The changing shape of indenting crustal blocks during northward motion of the Adriatic microplate induced migration of Miocene doming and orogen‐parallel extension of orogenic crust in the Tauern Window. New structural and kinematic data indicate that initial shortening of the Penninic nappe pile in the Tauern Window by upright folding and strike‐slip faulting was transitional to coeval north‐south shortening and east‐west extension; the latter was accommodated by normal faulting at the eastern and western margins of the window. Retrodeforming these post‐nappe structures in map view yields a map‐view reconstruction of the orogenic crust back to 30 Ma, including the onset of pronounced indentation at ~21 Ma. This model supports the notion that indentation involved approximately equal amounts of north‐south shortening and orogen‐parallel stretching and extrusion toward the Pannonian Basin, as measured from the indenter tip to the European foreland in the north and Austroalpine units in the east. Comparison of areal denudation of the orogenic crust before and after indentation indicates that erosion associated with upright folding was the primary agent of denudation, whereas extensional unroofing and limited erosion along normal faults at the eastern and western ends of the Tauern Window accounted for only about a third of the total denudation.
