Using the short-wave infrared spectral data obtained by the Zhurong rover, researchers identified hydrated sulfate/silica materials on the Amazonian terrain at the landing site. "These hydrated minerals are associated with bright-toned rocks, interpreted to be duricrust developed locally. The lithified duricrusts suggest that formation with substantial liquid water originates by either groundwater rising or subsurface ice melting. In situ evidence for aqueous activities identified at Zhurong’s landing site indicates a more active Amazonian hydrosphere for Mars than previously thought."
