La Méditerranée se situe dans une zone de convergence lente entre les plaques Eurasienne et Africaine (~5 mm/an), où des restes d'anciens bassins Téthysiens sont progressivement consommés par le retrait rapide de zones de subductions (~20-30 mm/an sur la zone de subduction Helléniqu...

Eclogite and carpholitebearing metasedimentary rocks in the North Qilian suture zone, NW China:Implications for Early Palaeozoic cold oceanic subduction and water transport into mantle[J]. Journal of Metamorphic Geology, 2007, 25(5):547-563. doi: 10.1111/jmg.2007.25.issue-5 CrossRef Google ...
(MSWD = 1.3), which proves that the formation time of the island-arc type magmatite in the northern zone of West Qinling is Late Ordovician or Early Silurian, also reveals that the timing of subduction of paleo-ocean basin represented by the Guanzizhen ophiolite and resulting island-arc-...
In this study, we present petrological and geochemical evidence of high-pressure serpentine dehydra- tion which led to the formation Ti-Chn and Ti-Chu in the ultramafic rocks within the ISB. This metamorphic evolution of the ISB ultra- mafic rocks is comparable to modern subduction zone ...
Les zones de cisaillement délimitant l’IOGU sont clairement mises en évidence par les vecteurs d’induction des sondages ioz10 et ioz20 pour la shear zone ouest-ouzzalienne (WOSZ) et ioz90 et ioz105 pour la shear zone est-ouzzalienne (EOSZ) ( Fig. 4a). Par ailleurs, les ...
Mesozoic magmatic activities are widely distributed in the Bangong Co-Nujiang suture zone in Tibet, and it is important to study them for understanding the evolution of the Tethys Ocean. This paper reports the zircon U-Pb dating and zircon Hf isotope data of the andesites of the Qushenla Fo...
La collision Afrique–Europe durant l'Éocène entraı̂ne la surrection de la chaı̂ne atlasique, et l'individualisation des bassins phosphatés, aux deux extrémités de cette chaı̂ne, correspond alors à des blocs éjectés latéralement de part et d'autre de la zone compri...
The southwestern corner of the Gulf of Mexico (around the Isthmus of Tehuantepec) is exposed to intense deep (>100 km) seismic activity caused by the subduction of the Cocos Plate. Aside from this, the gulf has been considered a zone of ... ...
Pyrenees, the Cucugnan area (Southern Cor- bières) corresponded during the early/Mid-Paleocene (Danian/ Selandian) to a narrow transitional zone between the sea to the South ("Pyrenean Paleocene Trough") and the continent (fluvio-palustrine and lacustrine "Vitrollian" de- posits) to the ...
