Global geological mapping of Enceladus highlights 3 distinct tectonized regions, which we term trailing hemisphere terrain (THT), leading hemisphere terrain (LHT), and south polar terrain (SPT). All three terrains are framed by curvilinear terrain units, and all have comparable areal extent with the south polar terrain being the smallest. In its central region, the THT contains a unit consisting of smooth materials and long shallow troughs, which is nearly identical to materials of the SPT just northward of the "tiger stripes” and with similar orientation of SPT troughs. This suggests that these shallow troughs may have formed in a similar manner to the SPT fractures. In contrast to the SPT, the THT contains a ridged unit of large dorsa, cross-cutting a striated plains unit, all within the THT's frame of curvilinear terrain. The LHT contains a disorganized network of troughs similar to parts of the SPT. The LHT also has units with polygons of sub-parallel troughs suggesting shearing. Heavily cratered terrain reaches around the saturnian and anti-saturnian sides of the satellite, abutting the south polar terrain. We recognize a total of 13 different geological units within the three tectonized regions and the cratered terrain of Enceladus. Differences in the local terrains might be explained by combinations of local diapiric uplift, collapse, and satellite reorientation to form the tectonized terrains, tied to episodic localized heat flow related to tidal stresses.
