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...
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...
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....
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...
fluids. The hydrogen then supports the growth of thermophilic and hyperthermophilic autotrophs, particularly methanogens such as theMethanococcales. In contrast, along subduction zones where highly weathered seafloor that is millions of years old is melted and reacts with seawater, the hydrothermal ...
This occurred in relation to shear zones, lithospheric thinning, asthenospheric upwelling, and partial melting of subduction-related enriched SCLM domains. The Variscan basement of the Catalan Coastal Range and Eastern Pyrenees record the transition from a contractional or transpressional tectonic ...
