A descriptor term used in the Gazetteer of Planetary Nomenclature.
Extension of plateau having rounded lobate or tonguelike boundaries (IAU Gazetteer 2014).
Origin of Term
Lingua: tongue, Latin; lingula (dim.), small tongue.
This term is assigned to features on Mars (van der Hucht 2006, p. 123). These features were previously named lobes (e.g., Ultimi Lobe) (e.g., Vasavada et al. 2000). The two main parts of the north polar cap of Mars are referred to as “main lobe” and “Gemina Lingula Lobe” (Putzig et al. 2009); a hypothesized former extension of the north polar cap is termed Olympia Lobe (corresponding to the dune-covered Olympia Planum) (Fishbaugh and Head 2000).
