内容記述 | Poleward-facing slopes are preferentially flattened more than equatorward-facing slopes in middle latitudes on Mars. In this study, we confirm whether the preferential flattening of poleward-facing slopes was formed during the Amazonian, based on statistical investigation of impact craters on the relatively new surface of the Alba Patera region. In most cases, the angle of the poleward-facing wall is lower than that of the equatorward-facing wall of each crater at latitudes from 35 deg N to over 50 deg N. Shallow craters have both poleward-facing walls, the surface of which seems to be covered with ice-rich material, and floors which tend slightly to incline toward poleward. This may suggest that repeated formation and downward deformation of ice-rich mantling on poleward-facing walls, which is interpreted to have been formed at high obliquity, result in the formation of thick ice-rich infilling. Poleward-facing slopes may be preferentially flattened by the ice-rich deposits rather than erosional modification. | |||||
