Arabia Terra, Mars: tectonic and palaeoclimatic evolution of a remarkable sector of martian lithosphere

Abstract. A regional geologic study of Arabia Terra, a densely cratered area of Mars northern hemisphere, has revealed the individuality of this province. This is best expressed by an equatorial belt with a crater age distinctly younger as compared to the northern part of Arabia Terra and to Noachis...
