Dissolution origin of Ontario Lacus on Titan: evidences from geomorphological mapping, terrestrial analogs (Namibia) and laboratory experiments

Abstract : We compiled an interpretative geomorphological map of this region by merging all these datasets and by making comparisons with terrestrial landforms that closely resemble Titan's lakes: the Etosha pans in Namibia [6]. These terrestrial analogs develop through dissolution process under a semi-arid climate that is probably similar to Titan's climate [6,7]. On the basis of this analogy, we discuss the formation process of Ontario Lacus and other lakes on Titan.
