fauna [3]). Some might suggest that the island home of every member of the relevant trans-Atlantic clade (Hispaniola, Fuerteventura, Mallorca, Menorca, Elba) would actually imply that this lineage was an active and successful disperser at times, instead of being only a passive passenger on tectonic plates. Rather than providing a definitive answer, our results and conclusions highlight the diff...

In the paper the approach based on considerable non-uniformity of electric properties of lithosphere both by depth and by area is developed. Geoelectric sections (GES) of various types of continental lithosphere (rift hollows, crystalline massif, permafrost) to large depths are examined. The substantiation of models of the lithosphere electric conductivity in seismically active and stable areas...

The rugged mountainous regions of the deep seafloor hold both great scientific interest as well a host of difficult challenges for autonomous robots. Exploiting its abilities for precise navigation, trackline following, and bottom-following in rough terrain, the Autonomous Benthic Explorer (ABE) collected fine-scale bathymetry, magnetics, temperature, optical backscatter, and conductivity over ...

Introduction: Since its arrival at the Saturnian system, the Cassini spacecraft has made about 100 Titan flybys. The surface of Titan has been revealed almost globally by the Cassini observations in the infrared and regionally to about 25% in radar wavelengths [1,2,3] as well as locally by the Huygens optical instruments [4]. Extended dune fields, lakes, distinct landscapes of volcanic and tect...

The method of breakpoint-match-tracing is a new numerical simulation one to reconstruct the fault deformation process in three-dimensional space. This method, however, based on the spatial data relationship of three dimensional geological bodies, will reconstruct their original relationship result from using match path to trace the breakpoint and computation. Through picking up the breakpoint i...

lake maharlu basin is located in a synclinal valley of the folded zagros. the frame and rugged structure of the basin is made of three units of mountainous geomorphologic, smooth levels and tectonic hole and evolved during several geological periods under the effect of interactive relations of tectonic, climatology and hydro geomorphologic processes. in this study, the researchers applied histo...

[1] The tectonic evolution of Mars has been driven primarily by the interaction of Tharsisinduced loading stresses with a uniform contractional stress field, leading to global assemblages of graben and wrinkle ridges. Until recently, strike-slip faults have appeared to be largely absent from the tectonic record. We here present evidence for a new set of Noachian to Early Hesperian strike-slip f...

The Mediterranean climate prevailing on the coastal belt of the Mediterranean Sea undergoes to change toward the inner part of the Anatolia in accordance with the increase of altitude, mountain range barriers, the tectonic structure of the region, and tectonic-karstic depressions. Continentality also plays a critical role in the micro-climates that prevail across the various eco-regions. This s...

Abundant and clearly exposed relationships between structures and syntectonic sedimentary rocks in the southern Pyrenees make this area particularly suitable for detailed studies of the sequential development of a collisional orogenic belt. During the Pyrenean orogeny, major shortening occurred in the eastern Pyrenees in Eocene and early Oligocene times. Unto now, individual tectonic and deposi...
