Extended Data Fig. 8: Initial and post-relaxed crustal structures for basins with different formation times.
From: Obliteration of ancient impact basins on the Moon by viscous relaxation
Each plot presents the initial (dashed line) and post-relaxation topographies and crust-mantle interface profiles (solid lines) for basins formed 50 (red), 100 (blue), and 150 Myr (green) after tLMO. The numbers at the bottom of each plot report the relaxation factor. The upper panel shows the basins on the nearside (Tc=30 km) while the lower panel shows the basins on the farside (Tc=40 km). The pre-relaxed basin structures (dashed line) are from the impact simulations. a and d show the pre- and post-relaxed structures for basins with a diameter of 400 km, while b and e depict the structures for basins with a diameter of 800 km, and c and f represent the structures for basin with a diameter of 1,500 km. We note that for basin with D ~ 1,500 km formed at 150 Myr after tLMO on the nearside, we consider the crust thickness of zero in the basin interior (see c). The number in bracket at the bottom of c represents the relaxation factor for this case.
