Abstract Tectonically active remnants of Neo-Tethys represented by Mediterranean and western Pacific marginal seas are characterized by rapidly propagating backarc extension episodes. These appear to be triggered by random subduction nucleation events, commonly signalled by the appearance of refractory boninites in volcanic ‘proto-arcs’. As backarc basins evolve, active arcs separate from their ‘proto-arc’ remnants and may split again if more than one basin-opening episode occurs. Accreting arc…

Geochemical discrimination of tectonic setting for Devonian basalts of the Yarrol Province of the New England Orogen, central coastal Queensland: An empirical approach

Fault blocks and inliers of uppermost Silurian to Middle Devonian strata in the Yarrol Province of central coastal Queensland have been interpreted either as island-arc deposits or as a

Time-progressive mantle-melt evolution and magma production in a Tethyan marginal sea: A case study of the Albanide-Hellenide ophiolites

We present a comprehensive overview of the melt evolution of the upper mantle peridotites and different lava types occurring in the Jurassic Albanide-Hellenide ophiolites, based on new and extant

Structural architecture of the Western Alpine Ophiolites, and the Jurassic seafloor spreading tectonics of the Alpine Tethys

We present a regional synthesis of the structural architecture and tectonic evolution of the Western Alpine Ophiolites (WAO), exposed in NW Italy. The WAO represent the remnants of Alpine Tethys

Abstract Ophiolites show a wide range of internal structure, pseudostratigraphy and chemical fingerprints suggesting various tectonic settings of their origin. In general, they are characterized as

Abstract Early Carboniferous–Eocene units exposed in the Arvin area document the development of the southerly, active continental margin of Eurasia. The oldest rocks exposed in the area are Early

Magma generation and crustal accretion as evidenced by supra‐subduction ophiolites of the Albanide–Hellenide Subpelagonian zone

Abstract  Ophiolites of the Mirdita–Subpelagonian zone form a nearly continuous belt in the Albanide–Hellenide orogen, including mid‐ocean ridge basalt (MORB) associations in the western Mirdita

We present an overview of the internal structure of the ophiolite massifs along the Yarlung Zangbo suture zone (YZSZ) in southern Tibet with a focus on the geochemical character and tectonic



The Oman ophiolite as a Cretaceous arc-basin complex: evidence and implications

Geological and geochemical evidence suggest that the Oman ophiolite is a fragment of a submarine arc-basin complex formed above a short-lived subduction zone in the mid-Cretaceous. Detailed studies

Initiation of subduction zones along transform and accreting plate boundaries, triple-junction evolution, and forearc spreading centres—implications for ophiolitic geology and obduction

Summary Most large ophiolite complexes have been interpreted as representing the obducted remnants of oceanic basement of forearc regions. A knowledge of the tectonic setting of ophiolite formation

New evidence for crustal accretion in the outer Mariana fore arc: Cretaceous radiolarian cherts and mid-ocean ridge basalt-like lavas

New age determinations on radiolarian cherts, foraminifers, and volcanic rocks document the presence of allochthonous fragments of Cretaceous oceanic plate, suggesting accreted terrane, in the outer

Tethyan ophiolites, mantle convection, and tectonic "historical contingency": A resolution of the "ophiolite conundrum"

The "ophiolite conundrum" describes the conflict in many ophiolite complexes between (1) structural and stratigraphic evidence for seafloor spreading in a non-island-arc environment and (2)


In the Albanian ophiolites, as well as in many other ophiolite complexes, tectonic, magmatic and geochronological evidences support the view that the intra- oceanic detachment preceding obduction is
