It remains controversial whether burial and exhumation in mountain belts represent episodic or continuous processes. Regional patterns of crystallization and closure ages of high-pressure rocks may help to discriminate one mode from the other but, unfortunately, metamorphic geochronology suffers from several limitations. Consequently, no consensus exists on the timing of high-pressure metamorphic events, even for the Alps—which have been the subject of two centuries of field work. Here we… 

Timing of high-pressure metamorphic events in the Bulgarian Rhodopes from Lu–Hf garnet geochronology

Within the Mediterranean realm, the Rhodopes represent a nappe stack of oceanic and continental fragments assembled along the Eurasian continental margin during the Alpine orogeny. The timing of the

Subduction-related metamorphism in the Alps: review of isotopic ages based on petrology and their geodynamic consequences

Abstract We summarize ages of the high‐pressure/low‐temperature (HP/LT) metamorphic evolution of the central and the western Alps. The individual isotopic mineral ages are interpreted to represent

Dating the initiation of Piemonte-Liguria Ocean subduction: Lu–Hf garnet chronometry of eclogites from the Theodul Glacier Unit (Zermatt-Saas zone, Switzerland)

The Penninic nappe stack in the Central and Western Alps was formed in a collision zone environment after the closure of the Penninic oceans in the Paleogene. This study reports Lu–Hf garnet-whole

Two high-pressure metamorphic events, Variscan and Alpine, dated by Lu–Hf in an eclogite complex of the Austroalpine nappes (Schobergruppe, Austria)

The Eo-Alpine high-pressure belt in the Austroalpine nappes consists of pre-Mesozoic basement rocks overprinted by eclogite-facies metamorphism during the Late Cretaceous. Parts of this basement were



Pb−Sr−Nd isotopic behavior of deeply subducted crustal rocks from the Dora Maira Massif, Western Alps, Italy-II: what is the age of the ultrahigh-pressure metamorphism?

Pb, Nd and Sr isotope data are reported from two localities on mineral separates from Mg-rich metapelites and associated rocks that have been subducted to depths of at least 100 km, for which

Ultrahigh Pressure Metamorphism: Ultra-high-pressure metamorphic rocks in the Western Alps

Abstract The focus of this paper is on the UHP rocks of the western Alps and particularly on the southern Dora-Maira massif where demonstrated coherency and a wide range of lithologies preserve UHP

Sm-Nd isotopic evidence on the age of eclogitization in the Zermatt-Saas ophiolite

Rocks within the Zermatt-Saas ophiolite of the western Alps have undergone eclogite facies metamorphism during subduction prior to the Alpine collision. The metamorphic history of these rocks is well

Garnet peridotite and eclogite Sm-Nd mineral ages from the Lepontine dome (Swiss Alps): New evidence for Eocene high-pressure metamorphism in the central Alps

In the central Alps the upper Pennine Cima Lunga nappe (Lepontine dome, Swiss Alps) underwent eclogite facies conditions up to 850-900 °C and 3.5-4.2 GPa. Sm-Nd dating of garnet peridotites and an

U-Pb zircon, Rb-Sr and Sm-Nd geochronology of high- to very-high-pressure meta-acidic rocks from the western Alps

Three meta-acidic rocks from the western Italian Alps, a magnesiochloritoid-bearing “metapelite” from the Monte Rosa massif, a coesite-pyrope-“quartzite” from the Dora Maira massif and the Monte

Old lead components in the young Bergell Massif, south-east Swiss Alps

The time of emplacement and origin of the Bergell Massif is considered in the light of recent isotopic investigations, particularly U + Pb in zircons. Zircons from the three main types of granitic
