• Resumen

  • Conamara Chaos is one of the most studied chaotic terrains on Europa (satellite of Jupiter). It is located at 8QN, 274eW. The structural analysis shows two different tectonic episodes over a relic background have been recognised and described in Europa, both with strike-slip regimes: ancient faultsaffected by active faults according to a present-day stress tensor. The strike-slip regime implicatescompressive structures (reverse faults) due to horizontal movements in the Europa surface. Active faultfamily has a greater fractal dimension (1.77) than ancient faults (1.41). Therefore, active faults are formed by re-activated and new-formed faults. Fracturing density and geostatiscs analysis are robust withthis explanation and complete the structural and tectonic knowledge of Conamara Chaos.
