Numerical model of mountain building
Показать описание
TOP: In this numerical model, the bottom of the box (just below the blue layer) represents the plate that is moving to the left. This pushes the overlying crust against the left side of the box, similar to the process of building mountains in orogenic wedges. The stripes of the crust are just there so you can see how individual rocks are deformed. The blue material on the base is a weak layer that slips more easily than the overriding rock.
BOTTOM: Colors show predicted strain rate. Black areas are not deforming. Bright light areas are zones of focused deformation in "shear bands" which simulate fault zones.
