Extended Data Fig. 9: Topographic diffusion for basins with different formation times.
From: Obliteration of ancient impact basins on the Moon by viscous relaxation
The topographic profiles from the young and well-preserved Schrödinger and Orientale basin are used as the initial profiles for basins of 300 km (a) and 800 km (b) in diameter. For D ~ 1,500 km basins, we stretch the topographic profile of Orientale by a factor of ~1.6 in diameter to represent the initial topographic structure (c). Assuming these basins formed 4.30, 4.25, 4.20, and 3.85 Gyr ago, their topographies are modified by subsequent impact events.
