The volcanology of Idunn Mons, Venus: The complex evolution of a possible active volcano

Idunn Mons is a shield volcano located in the Imdr Regio large igneous rise, Venusian equivalent to hotspot geologic province on Earth. Recent studies using emissivity data from ESA's Venus Express Mission, together with experimental laboratory alteration of volcanic materials conditions, suggest that possible site for very recent or even ongoing activity. In this work we carried out mapping characterize its and structures establish evolution. This study suggests analogous oceanic island volcanoes Earth, constructive phases alternate flank collapse episodes, resulting flat-topped summit morphology. These events can be related intimate temporal spatial relationship existing between Olapa Chasma, rift dominates rise relates evolution, suggesting not simply candidate active volcanism but also tectonism.
