..., refered to as the Peridotite nappe, is thrusted over the basaltic formations of the Poya terrane which are classicaly thought to originate from a different oceanic environment; 3) The basal contact of the ultramafic sheet is remarkably flat all along New-Caledonia and the Peridotite nappe has not been...

... reconstructions ( Crowley et al . 2000 ; Tait et al . 2000 ; Matte 2001 ). The OMZ, placed between the two sutures, was an independent terrane, although it must have always been closely tied to the Gondwana margin, given that palaeobiological data do not support the existence of a wide Palaeozoic ocean...

... ). These are tectonically inter-stratified with regionally extensive basalts, dolerites, gabbros, and associated cherts and volcaniclastic rocks known as the Formation des Basaltes ( Paris, 1981 ) or Poya terrane ( Cluzel et al., 1995a ; Cluzel, 1996 ). Basalts are predominantly tholeiites with enriched mid-oceanic-ridge...

Beneath the Lapland Granulite Belt and neighbouring northern portion of the Belomorian terrane the Moho deepens to more than 44 km. In the area...
