Hence, we suggest that the Thores volcanic island arc was closely associated with age equivalent arcs developed within the northern Iapetus Ocean. Its juxtaposition with the other successions of the Pearya Terrane is explained by a large-scale, left lateral, strike-slip system operating along the...

The large ooidal deposit discovered off the eastern coast of Panarea Island is hosted by a volcanic edifice that has evolved between 155 and 8.7 ka, following various stages of activity: between 155–149 ka the central apparatus developed then, the island of Panarea formed between 124 and 118...
2). The Monte Castelo gabbro is similar in composition to modern island-arc basalts [8]. The Corredoiras orthogneiss is granodioritic to tonalitic [40], whereas a minor gabbroic intrusion in the Cabo Ortegal Complex is calc-alkaline and characteristic of a volcanic arc setting [18]. The ...
The North China craton (NCC) was dominated by tectonic extension from late Cretaceous to Cenozoic, yet seismic studies on the relationship between crust extension and lithospheric mantle deformation are scarce. Here we present a three dimensional radiall
This means that arc volcanics without evidence that they formed at ocean ridges should not be called ophiolites. Ophiolites should preserve one or more of the definitive components (such as sheeted dykes, podiform chromite, and serpentinized harzburgite). Although ophiolites have been reported in...
