Abstract

The origin and formation of strange seasonal patterns on frost-covered Martian polar terrain is a great enigma. Their latest grouping was given by [1] classifying them into spots, fans, blotches, and halos, where fans are analyzed in details by [2, 3] and probably formed by geyser-like activity [4]. In the analysis of defrosting structures, polar dunes are particularly interesting because they trap the frost for longer period than the surrounding terrain [5] and show gullies formed possibly by melting of ice recently [6]. The aim of our work is to correlate two kinds of spot appearance with surface temperature values in order to eliminate whether they could have formed by melting or not.
