The present-day northern Apennines represent an area where two different orogenic cycles took place. The most ancient is the Alpine Orogeny, initiated with a south- to south-eastward subduction of oceanic lithosphere (Early Cretaceous to Late Eocene phase), followed by continental collision. The younger is referred to the Apennines Orogeny, characterized by a west- to north-westward oceanic lithosphere...
Extensive late Paleozoic mafic–ultramafic complexes in the Eastern Tianshan and Beishan regions in the southern Central Asian Orogenic Belt (CAOB) represent an ideal opportunity to assess the characteristics of the mantle in this area. Whole-rock Nd–Sr and zircon Hf–O isotopic data from the mafic–ultramafic complexes of the Jueluotage Belt, Middle Tianshan Massif and Beishan Rift were compiled for...
The Western Iratsu body of the Sanbagawa belt (SW Japan) represents a <2km thick garnet–epidote amphibolite slice with minor intercalated occurrences of eclogite. Equilibrium phase assemblage diagrams (pseudosections) for eclogite and garnet–epidote amphibolite from this body can be successfully used to reconstruct the pressure (P)–temperature (T) path and the evolution of the associated mineral...
A high-resolution U–Pb zircon geochronological study of plutonic units along the south Peruvian margin between 17° and 18°S allows the integration of the geochemical, geodynamic and tectonic evolution of this part of the Andean margin. This study focuses on the composite Jurassic–early Cretaceous Ilo Batholith that was emplaced along the southern Peruvian coast during two episodes of intrusive magmatism;...
The Cenozoic magmatic record within the ca. 500km long eastern Pontides orogen, located within the Alpine metallogenic belt, is critical to evaluate the tectonic history and geodynamic evolution of the eastern Mediterranean region. In this paper we report for the first time late Miocene adakitic rocks from the southeastern part of the eastern Pontides belt and present results from geochemical and...
The Alborz Magmatic Assemblage (AMA) is an Eocene volcanic complex in northern Iran, and is situated at the site of the closure of the Tethyan basin. The magmatic rocks of the Alborz assemblage exhibit a distinct progression in style, from shallow submarine explosive eruptions to more effusive sub-aerial eruptions. Their chemical compositions indicate that they belong to the high-K calc‐alkaline (shoshonitic)...
The Wagonga Group at Batemans Bay and Narooma contains basalt clasts in mélange and basaltic breccia units. At Batemans Bay the basalt breccia unit is associated with Middle to Late Cambrian parautochthonous limestone beds and clasts. They have been altered by hydrothermal fluids and during tectonic burial producing prehnite pumpellyite facies assemblages. Subsequently, they were taken to greater...
