In a fault, movement or slip that is intermediate in orientation between the dip slip and the strike slip. Compare: strike slip
Industry:Mining
In a fault, the component of the movement or slip that is parallel to the dip of the fault. Compare: dip separation; strike slip; oblique slip; total displacement; dip shift.
Industry:Mining
In a fault, the distance measured vertically between two parts of a displaced marker such as a bed. Compare: horizontal separation
Industry:Mining
In a fault, the horizontal component of separation measured parallel to the strike of the strata, with the faulted bed absent from the measured interval.
Industry:Mining
In a fault, the shift or relative displacement of the rock units parallel to the dip of the fault, but outside the fault zone itself. Compare: dip slip; strike shift.
Industry:Mining
In a filter, the difference between the nominal upper and lower cutoff frequencies. This difference may be expressed in cycles per second, as a percentage of the pass-band center frequency, or as the difference between the upper and lower cutoffs in octaves.
Industry:Mining
In a four-stroke internal combustion engine two complete revolutions of the crankshaft correspond with the working cycle-inlet stroke (suction downstroke of piston in cylinder); compression upstroke; explosion at peak of compression followed by expansion of hot exploded gases on driving downstroke; rising exhaust stroke to complete the cycle.
