"WebIn geology, the terms sinistral and dextral refer to the horizontal component of movement of blocks on either side of a fault or the sense of movement within a shear zone. These are terms of relative direction, as the movement of the blocks is described relative to each other when viewed from above. Movement is sinistral (left-handed) if the ...

Web1 de ago. de 1995 · In this case, the dip of the normal faults, whose geometry becomes planar, decreases with increasing thrust dip. We suggest that this change in dip of normal faults depends upon the rotation of stress tensor axes along the pre-existing fault zone, where a drop in the friction coefficient is likely to occur; (c) reactivation occurs in brittle …

A releasing bend or step produces a component of extension, leading to formation of a pull-apart basin. A restraining bend or step results compressional stresses, often causing uplift in that region. For a right-lateral strike-slip fault, a right bend or step is releasing; likewise, for a left-lateral fault, a left bend or ...

WebThis left-lateral oblique-slip fault suggests both normal faulting and strike-slip faulting. It is caused by a combination of shearing and tensional forces. Nearly all faults will have some component of both dip-slip (normal or reverse) and strike-slip, so defining a fault as oblique requires both dip and strike components to be measurable and significant.
