Fig. 7From: Evolution of the rheological structure of MarsStrength profiles of the past Martian highlands (Solis Planum). Based on the temperature profile (Fig. 4b), the rheological structure of the Martian highlands every 1 billion years is calculated as per Fig. 5. The strain rate is assumed to be 10−16 (solid line) or 10−19 s−1 (dashed line)Back to article page
