SHIFT It frequently happens that a fault has not a single surface of shear. but consists of a series of small slips on closely spaced surfaces, and in some faults the strata in the neighborhood of the fault surface are bent. so that the relative displacements of the rock masses on opposite sides of the fault may be quite different from the slip and not even parallel with it. The word "shift" is used to denote the relative displacements of the rock masses situated outside the zone of dislocation: the qualifying. Figuee 4.—The Shift words relate to the strike and dip of the fault with one exception, in which the meaning is clear. The shift, or net shift, denotes the maximum relative displacement of points on opposite sides of the fault and far enough from it to be outside the dislocated zone: de in figures 3 and -i. where d is the position of a selected point before and e after the faulting. The strike-shift is the component of the shift parallel with the fault- strike ; df in figures 3 and 4. The dip-shift is the component of the shift parallel with the fault dip; Spurr calls this the '"lateral Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Geological Society of America.
