Quantitative assessment of relative tectonic activity in the Alamarvdasht river basin, south of Iran
Tectonic processes are major factors controlling landform development in tectonically active areas. In order to evaluate quantitative measurement of tectonic activities in the Alamarvdasht basin in the south of Iran, six different morphological indices including stream-gradient index (SL), drainage basin asymmetry (Af), hypsometric integral (Hi), valley floor width-valley height ratio (Vf), dra...
متن کاملThe hemispheric dichotomy of surface tectonics and heat flux on Enceladus
Enceladus exhibits a strong tectonic contrast between its South Polar Terrain (SPT), which is young and geologically active, and its northern hemisphere, which is relatively ancient and stable. Previous global three-dimensional spherical models of convection exhibit patterns that are symmetrical around the equator and fail to explain the formation of a hemispheric dichotomy. Here we present glo...
متن کاملEnceladus: An Active Cryovolcanic Satellite
Enceladus is one of the most remarkable satellites in the solar system, as revealed by Cassini’s detection of active plumes erupting from warm fractures near its south pole. This discovery makes Enceladus the only icy satellite known to exhibit ongoing internally driven geological activity. The activity is presumably powered by tidal heating maintained by Enceladus’ 2:1 mean-motion resonance wi...
متن کاملCassini observes the active south pole of Enceladus.
Cassini has identified a geologically active province at the south pole of Saturn's moon Enceladus. In images acquired by the Imaging Science Subsystem (ISS), this region is circumscribed by a chain of folded ridges and troughs at approximately 55 degrees S latitude. The terrain southward of this boundary is distinguished by its albedo and color contrasts, elevated temperatures, extreme geologi...
متن کاملEstablishing a Long-term Fracture History of the South Polar Terrain on Enceladus
Introduction: Enceladus is the sixth-largest moon of Saturn and has a diameter of approximately 504 km. The icy moon synchronously orbits Saturn at a distance of approximately 238,000 km once every 33 hours between Mimas and Tethys [1] but is locked in a 1:2 resonance with Dione resulting in an orbital eccentricity of 0.0047 [2]. However, Enceladus is very different from other Saturnian moons, ...
