STRIKE-SLIP RUPTURE PATTERNS IN SAND MODELS

Sand, in models of strike-slip deformation yields ruptures that suggest a genetic relationship between the fundamental drive in the form of horizontal translation and such possibly related phenomena as: 1. (1) concomitant dip-slip displacements at the surface. 2. (2) proliferation of ruptures at and near the surface to generate a rift pattern. 3. (3) segmentation into blocks by these ruptures, freeing them for discrete displacement relative to each other. 4. (4) thereby the creation of welts (horsts) and grabens in the rift pattern. 5. (5) adjoining arcuate thrusts, more strongly developed in a curved fundamental displacement. 6. (6) plateau type of uplift, and rises above and consequent to these thrusts. © 1969.
