A cycloid is a series of linked arcuate segments. Cycloids have been observed on Europa at both global and regional scales and with a variety of morphologies. Some appear to be hairline fractures, while others have well-developed flanking ridges. Several wide bands have been identified with the characteristic linked segment morphology of cycloids, and many of these also exhibit strike-slip offsets (Kattenhorn and Hurford 2009, and references therein).


Widths similar to other cracks, ridges, and bands. Ridges consisting of multiple segments up to >1,000 km long (Fig. 1).
