英文摘要 | A striking feature of Gale crater is the 5.5km high, central layered mound called Mount Sharp (Aeolis Mons)the major exploration target for the Mars Science Laboratory rover, Curiosity. Within the 154km diameter crater, low plains (Aeolis Palous) resemble a moat surrounding Mount Sharp. There is a similar terrestrial analog in the Jurassic Navajo Sandstone of southern Utah, USA, where a distinctive weathering pit 60m wide by 20m deep contains a central pillar/mound and moat. Strong regional and local winds are funneled to amplify their velocity and produce a Venturi effect that sculpts the pit via wind abrasion. Although the Navajo pit is orders of magnitude smaller than Gale crater, both show comparable morphologies accompanied by erosional wind features. The terrestrial example shows the impact of weathering and the ability of strong winds and vortices to shape lithified sedimentary rock over long periods of time. |
