Integrating in situ Geochronology and Metamorphic Petrology: An Example from the Gruf Complex, European Central Alps
… and modern orogenies. Ultra-high temperature (UHT) metamorphism requires geodynamic or tectonic processes that bring excess heat to the lower crust. Therefore, dating UHT metamorphism can shed light on the geodynamic evolution of the geological settings in which UHT rocks are exposed. In recent …

Metamorphic evolution of ultrahigh-temperature granulite facies and upper amphibolite facies rocks of the Epupa Complex, NW Namibia
… rocks (Orue Unit) and (2) ultrahigh-temperature (UHT) granulite facies rocks (Epembe Unit). The rocks of the EC are transsected by a large anorthosite massif, the Kunene Intrusive Complex (KIC). The Orue Unit and the Epembe Unit were affected by two distinct Mesoproterozoic metamorphic events, as …

On Ultra-High Temperature Metamorphism in the Mid-Lower Crust
… natural example of ultra-high temperature (UHT) metamorphic processes and country rock-magma interaction due to mappable units of hybrid igneous rocks and the presence of large, partially melted, politic "emery" xenoliths. Previous attempts to understand the formation of the UHT xenoliths in …

Metamorphic and crustal evolution of Australian-Antarctic Proterozoic margins
… Myr), high temperature–ultrahigh temperature (HT–UHT) metamorphism challenges conventional notions on the thermal state of the crust as it requires the sustaining of high energy thermal gradients (>>75 °C/kbar). Regional, long-lived, high thermal gradient metamorphism occurring at continental …
