不好意思,荼毒一下大家的眼睛...蝌蚪文一堆...不過可以綜合一下、釐清一下~~^^
前面的大大說的都是棒的啦~我順水插花一下...
Transform fault:
a. A strike-slip fault that links two other faults or two other plate
boundaries (e.g. two segments of a mid-ocean ridge). Transform faults often
exhibit characteristics that distinguish them from transcurrent faults:
(1) For transform faults formed at the same time as the faults they link,
slip on the transform fault has equal magnitude at all points along the
transform; slip magnitude on the transform fault can exceed the length of the
transform fault, and slip does not decrease to zero at the fault termini.
(2) For transform faults linking two similar features, e.g. if two mid-ocean
ridge segments linked by a transform have equal spreading rates, then the
length of the transform does not change as slip accrues on it.
b. A type of plate boundary at which lithosphere is neither created or
destroyed, and plates slide past each other on a strike-slip fault.
Cf: transcurrent fault.
Transcurrent fault:
A type of strike-slip fault where (1) the magnitude of slip on the
fault is less than the length of the fault; (2) fault displacement is
greatest near the midpoint of the fault and is zero at the fault tips;
(3) the fault progressively increases in length as its magnitude of slip
increases; (4) the fault does not terminate at plate boundaries.
Cf. transform fault.
