About the cover:
Sandbox model of orogenic wedge submitted to erosion illustrating the impact of décollements. Deformation partitioning is characterized from right to left by a frontal imbricate of thrust sheets; a synformal stack of thrust units (resting above the décollement); and an antiformal stack of underplated thrust units (image by E. Konstantinovskaia and J. Malavieille). See “Impact of erosion, sedimentation, and structural heritage on the structure and kinematics of orogenic wedges: Analog models and case studies,” by J. Malavieille, p. 4–10.
