That solid sulfate mineral crust contrasts with thinner, weaker duricrusts observed by other Mars rovers, which may have formed through the actions of water vapor, according to the study.

根据这项研究，固体硫酸盐矿物外壳与其他火星探测器观察到的更薄、更弱的硬壳形成鲜明对比，硬壳可能是通过水蒸气的作用形成的。

They interpreted the bright-toned rocks Zhurong's camera caught as a layer of " duricrust" that would have been sculpted by a substantial quantity of liquid water, perhaps rising groundwater or melting subsurface ice.

他们将“祝融号”相机捕捉到的亮白岩石解释为一层“硬壳”，它可能是由大量液态水雕刻而成的，可能是上升的地下水或融化的地下冰。
