Earth is the only known planet with plate tectonics, which involves a mobile upper thermal boundary layer. Other terrestrial planets show a one-plate immobile lithosphere, or stagnant lid, that insulates and isolates their interior. Here, we first review the different types of lids that can develop on rocky and icy bodies. As they formed by accretion, involving high-energy impacts, terrestrial planets likely started hot and molten. We examine the process of lid initiation from a magma ocean stage and develop the equations for lid growth. We survey how lateral perturbations in lid and crust thickness can be amplified during their growth and finally discuss the possible processes at the origin of lid rupture and plate generation.

行星停滞盖子和地壳的形成和演变

地球是已知唯一具有板块构造的行星,这涉及一个移动的上热边界层。其他类地行星显示出一个单板固定的岩石圈,或停滞的盖子,隔离和隔离它们的内部。在这里,我们首先回顾了岩石和冰冷物体上可能形成的不同类型的眼睑。由于它们是由吸积形成的,涉及高能撞击,类地行星很可能一开始很热和熔融。我们研究了岩浆海洋阶段的盖子起始过程,并开发了盖子生长的方程。我们研究了盖子和外壳厚度的横向扰动在其生长过程中如何被放大,最后讨论了盖子破裂和板生成根源的可能过程。
