During late 1999/early 2000, the solid state imaging experiment on the Galileo spacecraft returned more than 100 high-resolution (5 to 500 meters per pixel) images of volcanically active Io. We observed an active lava lake, an active curtain of lava, active lava flows, calderas, mountains, plateaus, and plains. Several of the sulfur dioxide-rich plumes are erupting from distal flows, rather tha...

The recent discovery of super-Earths (masses ≤ 10 M⊕) has initiated a discussion about conditions for habitable worlds. Among these is the mode of convection, which influences a planet’s thermal evolution and surface conditions. On Earth, plate tectonics has been proposed as a necessary condition for life. Here we show, that super-Earths will also have plate tectonics. We demonstrate that as pl...

Stratigraphic correlations presented here for the ductilely deformed and metamorphosed rocks exposed in the Shadow Mountains indicate that they formed on the North American continental margin and are not exotic or significantly displaced from their site of origin. These strata represent a depositional history that spans Late Proterozoic and Paleozoic passive margin development, late Paleozoic t...

The morphology of the Earth is a result of interactions between climate, tectonics, and geology and the investigation of neotectonics is one of the vital disciplines in Earth science, because the results of regional studies of active tectonics are significant for evaluating natural hazards as well as land use development and management in populated areas. In this regard neotectonic features of ...

Today, plate tectonics is the dominant tectonic style on Earth, but in a hotter Earth tectonics may have looked different due to the presence of more melting and associated compositional buoyancy as well as the presence of a weaker mantle and lithosphere. Here we review the geodynamic constraints on plate tectonics and proposed alternatives throughout Earth’s history. Observations suggest a 100...

Kosovo is located in a key position the central-west part of Balkans providing an opportunity to understand far-field effects distributed intracontinental deformation caused by Aegean extension south and Adriatic compression west. It also situated along NE-SW trending Shkodër-Pejë transverse zone, where Dinarides Albanides-Hellenides orogenic belts are juxtaposed. While instrumental seismicity ...
