Plate tectonics is one of the major factors affecting the potential habitability of a terrestrial planet. The physics of plate tectonics is, however, still far from being complete, leading to considerable uncertainty when discussing planetary habitability. Here, I summarize recent developments on the evolution of plate tectonics on Earth, which suggest a radically new view on Earth dynamics: co...

ABSTRACT Behavior of sediment gravity flows can be influenced by seafloor topography associated with salt structures; this modify the depositional architecture deep-water sedimentary systems. Typically, salt-influenced successions are poorly imaged in seismic reflection data, and exhumed systems rare, hence detailed sedimentology stratigraphic these remains understood. The Triassic (Keuper) Bak...

[1] Fluid distribution in convergent margins is by most accounts closely related to tectonics. This association has been widely studied at accretionary prisms, but at half of the Earth’s convergent margins, tectonic erosion grinds down overriding plates, and here fluid distribution and its relation to tectonics remain speculative. Here we present a new conceptual model for the hydrological syst...

To understand the evolution and the habitability of any rocky exoplanet demands detailed knowledge about its geophysical state and history—such as predicting the tectonic mode of a planet. Yetno astronomical observation can directly confirm or rule out the occurrence of plate tectonics on a given exoplanet. Moreover, the field of plate tectonics is still young—questioning whether we should stu...

[1] Although Mars is currently not tectonically active, it may have experienced plate tectonics early in its history. The southern hemisphere of Mars possesses a thick crust which probably renders the lithosphere positively buoyant. In this paper we present numerical and scaling arguments which show that if the area of positively buoyant lithosphere grows beyond a critical fraction ( 50% for Ma...

Introduction. Previous studies of initiation of plate tectonics were concerned mostly with the present-day Earth where plate tectonics is actively occurring [1-3]. Understanding of how plate tectonics starts and can be sustained for a long time on an Earth-like planet is a different problem. Investigation of this problem began only recently [4-6]. This problem is also important for understandin...
