Fig. 3From: Effects of magma-generation and migration on the expansion and contraction history of the MoonModel 1. We calculated this model by assuming \(M^{*} = 0\) in the reference model: only the effects of thermal diffusion, internal heating, and melting are considered, and the effects of magma migration are switched off. a–c Are the same as Fig. 2a, c, and e, respectively. In b the contour interval is 0.2 starting from 0 (indicated by the dashed line)Back to article page
