4) the frontal arc, a zone of uplift and deformation immediately between the accretionary
wedge and the volcanic chain;
At this latitude, the Palaeozoic accretionary
processes that occurred in the ancient southwestern margin of Gondwana start with the Cuyania collision to Gondwana (old Pampia terrane), causing to Famatinian orogeny in Ordovician times (Fig.
Detailed microscopic examination of the volcaniclastic (epiclastic) deposits was carried out, discriminating them into accretionary
lapilli tuff and finer grained hyaloclastite tuffs.
The Apennines subduction is characterised by compressional seismicity east of the chain, in the frontal accretionary
prism, and extensional tectonics to the west, associated to the opening of the Tyrrhenian backarc basin and slab rollback (Pondrelli et al.

wedge: sedimentology, structure and rheology.
1-2), while shell layers from organo-phosphatic brachiopods exhibit a concentric accretionary
pattern and sometimes a porous or granular texture (Fig.
They suggest that "existing survey information is inadequate to exclude the possibility of earlier Holocene human occupation" and predict that earlier sites may be found on low energy beach deposits and behind accretionary
coastal barriers (e.
Basin development in an accretionary
, oceanic-floored fore-arc setting: southern coastal Ecuador during Late Cretaceous-Late Eocene time, Am.
Eighteen contributed chapters honoring Windley's influence are arranged in sections on oceanic and island arc systems and continental growth, the tectonics of accretionary
orogens and continental growth, growth and stabilization of continental crust (collisions and intraplate processes), Precambrian tectonics and the birth of continents, and active tectonics and geomorphology of continental collision and growth zones.
However, traces of accretionary
lobes extending landwards to the south-east are evident along the southern shores of Al Aryam and suggest that the island is a composite of two former islands that probably nucleated on the vestiges of two(?
Structural style, diapirism and accretionary
episodes of the Sinu-San Jacinto Terrane, southwestern Caribbean borderland.
Genetically related "Bathymodiolus" populations also occur on the Barbados Accretionary
Prism (BAP) and have been referred to as "Bathymodiolus" sp.
