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...

Transform continental margins play a major role in plate tectonics. In the last 10 years' petroleum exploration has moved to hunt of stratigraphic traps passive margin sequence continent-ocean transforms. The result been drastic increase modern deep seismic data and more well calibrations. Considered as one longest transform boundaries, Davie system (East Africa) is best places investigate evol...

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...

The Chocó-Panamá block is the land bridge that connects Central and South America forms trailing edge of Caribbean Large Igneous Province (CLIP). New field observations are combined with new geochemical, isotopic 40Ar/39Ar analyses mafic basement Chocó within Colombia. These integrated U/Pb ages detrital zircons extracted from siliciclastic carbonate rocks unconformably overlie basement. data u...

We document the tectonic and metamorphic evolution of thrust nappes eastern island Elba. The area exposes a natural cross section Northern Apennines hinterland, from basement units to overlying continent- ocean-derived nappes. integrated mapping, analysis structures microstructures, interpretation drill core logs with lithostratigraphic, metamorphic, geochronological constraints, producing nove...

Plate tectonics is the horizontal motion of Earth’s thermal boundary layer (lithosphere) over the convecting mantle (asthenosphere) and is mostly driven by lithosphere sinking in subduction zones. Plate tectonics is an outstanding example of a self organizing, far from equilibrium complex system (SOFFECS), driven by the negative buoyancy of the thermal boundary layer and controlled by dissipati...

The long-term carbon cycle is vital for maintaining liquid water oceans on rocky planets due to the negative climate feedbacks involved in silicate weathering. Plate tectonics plays a crucial role in driving the long-term carbon cycle because it is responsible for CO2 degassing at ridges and arcs, the return of CO2 to the mantle through subduction, and supplying fresh, weatherable rock to the s...

The surface expressions of hydrothermal systems are prime targets for astrobiological exploration, and fossil systems on Earth provide an analogue to guide this endeavor. The Paleozoic Mt. Gee-Mt. Painter system (MGPS) in the Northern Flinders Ranges of South Australia is exceptionally well preserved and displays both a subsurface quartz sinter (boiling horizon) and remnants of aerial sinter po...
