Listwaenitization processes have significantly altered the mantle section of the West Chalkidiki ophiolites, generating the second largest magnesite deposit in Greece. Although research studies have been conducted in the region, the post-magmatic processes, and especially the geotectonic settings under which listwaenitization took place, remain unc...

S-type granites are striking products of supracrustal reworking and can provide crucial constraints on the anatexis of accretionary wedges in an accretionary orogen. In this study, we present new zircon and monazite dating results, whole-rock geochemistry, and zircon Lu-Hf isotopic data for the two-mica granites in the Muztagh area of the South Kun...

The Drosendorf Unit (DU) of Lower Austria has gained increasing attention during the past years as it contains many pre-Cadomian rocks (Gebauer and Friedl 1994; Lindner et al. 2020, 2021). These comprise 1.38-1.40 Ga old orthogneisses (Dobra Gneiss Type A, Hauergraben Gneiss), as well as metasedimentary rocks with an early Neoproterozoic deposition...

The Koralpe-Wölz nappe system, as part of the Austroalpine nappe complex, belongs to the crystalline basement of the Eastern Alps and is composed of different metasedimentary complexes with mono-, bi-, or polymetamorphic history (SCHMID et al., 2004; HABLER & THÖNI, 2001; THÖNO & MILLER, 2009). Very little is known about the protoliths of the Koral...

The Central European Variscan orogen consists of a mosaic of various peri-Gondwana terranes, which separated from Gondwana at various times during the Cambrian to Devonian. Later, during the Devonian-Carboniferous they were between the converging continents of Gondwana and Laurussia as the Rheic ocean closed. While the major part of the Bohemian Ma...

The discovery of an areally limited outcrop of blueschists in Huai Sak, near Ban Huai Lao, SE Nan Province in the early 1980s has not been followed up until now. This is despite these blueschists being used in many regional tectonic compilations as unequivocal evidence for the presence of a former subduction zone along the trend of the Nan river. W...

The Arabian–Nubian Shield (ANS), as a tract of Neoproterozoic juvenile island-arc suites and intervening oceanic basin, extends from Egypt/Saudi Arabia southwards along eastern Africa and is considered to end in southern Kenya where the southernmost ophiolite remnants occur. It consolidated by closure of the Mozambique Ocean and final collision of...

Polymetamorphic units are important constituents of continent-continent collisional orogens, and rift metamorphic assemblages are often overprinted by subsequent metamorphism during subduction and collision. This study reports the metamorphic conditions and evolution of the Dorud–Azna metamorphic units in the central part of the Sanandaj–Sirjan zon...

For a long time, the 1.38 Ga old Dobra Gneiss (Type A) from the Lower Austrian Drosendorf Unit (Moldanubian Zone, Bohemian Massif) was considered the oldest rock of Austria. We now have dated zircons from a local mafic inlayer in the Dobra Gneiss Type A, termed Hauergraben Gneiss. This small-scale amphibole-bearing orthogneiss has a magmatic format...

The Eoarchean Isua Supracrustal Belt (ISB) has been interpreted as one of the earliest records of subduction processes, leading to the conclusion that a plate tectonic geodynamic system was likely operating since the early Archean. However, proposed tectonic models remain difficult to evaluate as our understanding of the metamorphic and structural...

Late Mesozoic igneous rocks in Vietnam are predominantly found in the Dalat zone (southern Vietnam), but smaller volumes also occur within southernmost Indochina (SW Vietnam-SE Cambodia). Within the latter area, six different rock suites can be distinguished based on field relations, geochemical characteristics, and zircon UPb geochronology: (1) Ba...

Metasomatism is the prime process to create compositional heterogeneity of the upper mantle. Mineralogical and mineral chemical changes of the mantle triggered by metasomatism can be used to deduce the nature of the metasomatic agent(s) and to constrain the timing of metasomatism. This information is vital for an understanding of the secular evolut...

The Moldanubian Zone in Austria is traditionally subdivided into several tectonostratigraphic subunits, which were juxtaposed to their nowadays position during the Variscan orogeny. The Gföhl unit at the highest tectonic position exposes the Moldanubian granulites at the top, underlain by the granitic Gföhl orthogneiss. At its base lies the Raabs u...

Some (ultra)high-pressure metamorphic rocks that formed during continental collision preserve relict minerals, indicating a two-stage evolution: first, subduction to mantle depths and exhumation to the lower-crustal level (with simultaneous cooling), followed by intensive heating that can be characterized by a β-shaped pressure–temperature–time (P–...

Polyphase garnet growth, remnant mineral inclusions and textural relations indicate that most high-grade metamorphic rocks in the Austrian part of the Bohemian Massif are polymetamorphic. The method of in-situ EPMA Th-U-total Pb monazite dating provides an effective tool to constrain the age of different metamorphic events. Monazite in migmatitic p...
