WebThe progressive development of extensional fault geometries in a sedimentary cover sequence above a rigid or deforming basement has been experimentally investigated using analogue models. Quartz sand (700 μm) was used as a modelling material. The experiments were recorded using time-delay 16 mm cine photography and 35 mm photography. github workflow maven

Orthogonal extension is plausible in a process of the … WebBack-arc spreading is initiated with rifting along the volcanic zone of an island arc under extensional tectonics. The width of the volcanic zone of the arc, which is closely related to the dip angle of the subducting slab, should cause a variation in the style of initial rifting and subsequent back-arc spreading.
