RT Journal Article T1 Hecates Tholus, Marte: Inestabilidad del Edificio Volcánico T1 Hecates Tholus, Mars: Instability of the Volcanic Edifice A1 Pablo, Miguel Ángel de A1 López, Iván A1 Martín González, Fidel A1 Márquez, Álvaro AB Hecates Tholus is a volcano located at the Elysium volcanic province in the Martian lowlands (32ºN,210ºW). In addition to several nested calderas, the volcano shows several geological and geomorphologicalfeatures that could be indicative of a complex volcanic evolution: channels, depressions, pits, faults andridges, and a complex volcano topography. The processes that can explain the structural evolution of thevolcano, include: (1) volcanic spreading, (2) lateral volcanic activity, (3) development of large landslides,(4) hydrothermal activity, and (5) tectonic deformation. We discuss these hypotheses and their implications,in order to establish the most feasible volcanic history of Hecates Tholus YR 2007 FD 2007 LK http://hdl.handle.net/10272/8415 UL http://hdl.handle.net/10272/8415 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
