Geomorphological map of the South Belet Region of Titan

We mapped in detail Titan's South Belet region which spans from longitude 60°E to 120°E and latitude 60°S 0°, encompassing both equatorial southern mid-latitude regions. used Cassini RADAR its Synthetic Aperture Radar (SAR) mode data as our basemap, covers 31.8% of the region, supplemented with RADAR's radiometry mode, Imagining Science Subsystem (ISS), Visual Infrared Mapping Spectrometer (VIMS), topographic data. This mapping work is a continuation detailed global effort introduced Malaska et al. (2016a) continued Lopes (2020). followed procedure described for Afekan Crater identified four major terrain classes Belet: craters, hummocky/mountainous, plains, dunes. Each class was subdivided into units by characteristic morphology, including border shape, texture, general appearance, radar backscatter. There are two that were not included previous studies but “bright alluvial plains” “pitted hummocky”. Similar we find plains dominate surface make-up Belet, comprising ~47% area. Unlike Afekan, areal extent dunes closely rivals dominance making up 43% The next most widespread unit area following mountains/hummocky terrains (10%), finally, crater (0.01%). introduction new units, hummocky”, necessary capture full range morphologies seen expands understanding processes typical For example, presence fans indicates period past where discharges slopes such sediment could be mobilized deposited. Similarly, pits associated hummocky” may represent an important erosional feature, implications removal volatiles crust. However, analysis geomorphological results suggests geology consistent narrative organics dominating mid-latitudes. similar conclusion arrived at through region. Lastly, applicability bears northern hemisphere, latitudinal symmetry their evolution.
