Older subduction zones, which may have been active in this area when Andean-type magmatism was occurring on the edge of the New-England Orogen, have not been represented. An additional latest Jurassic–Early Cretaceous subduction zone may also be required to account for the closure of the ...
This NAM-SAM plate boundary zone, therefore must most certainly be heterogeneous in nature, exploiting weaknesses in the lithosphere provided by fracture zones where mechanically advantageous, but forming new boundary segments elsewhere, to transfer motion between reactivated segments of the fracture zones...
49,50, fault bends at depth51, the varying size of off-fault damage zones43,44, or the fault growth history52. Furthermore, zones of distributed deformation at fault tips can indicate fault propagation and termination towards the distributed deformation51,53. The...
The role of synsedimentary faulting is also made clear in the north of the Jbel Lkest massif, where the destruction of the quartzites generated breccias and conglomerates collected in topographic lows most likely associated with fault zones (O’Connor’s et al., 2010). Show abstract Coupled ...
Martinique and at 156 km depth along the subduction plane (Fig.1a). With a calculated PGA of up to 0.02 g along the Roseau Fault (Fig.7n), we expect this earthquake to have had limited impact on mass-wasting processes in the study area....
scale antiform structure formed by the present-day AR-MB massifs was shaped by the Alpine cycle (e.g. von Raumer and Bussy 2004; Rolland et al. 2008; Egli and Mancktelow 2013; Boutoux et al. 2016; Egli et al. 2017), rock deformation remained weak or localised within shear zones....
Dans certaines unités de socle anté-namurien, la nature polycyclique du métamorphisme est démontrée. Du point de vue structural, des zones de cisaille- ment ductiles et des plis isoclinaux à toutes échelles affectent ces unités. Distinguer un contact stratigraphique d'un contact tecto...
The eastern bend of the Cyprus Arc, at the transition between the submerged Mediterranean subduction and the onshore fault zones that underline the Eurasian, African and Arabic plates boundaries is a submarine feature undergoing a complex tectonic deformation. The BLAC marine geophysical survey helps ...
