The geometry of a dyke swarm as a result of dyke interaction with each other and with external stresses

Subsurface Geometry and Emplacement Conditions of a Giant Dike System in Elysium Fossae, Mars

“…This subsurface geometry fits well with the teardrop‐shape model for dikes propagating laterally from the volcanic center and under a non‐uniform topography (Corbi et al., 2015; Parfitt, 1991). This geometry is found consistently in modeling studies (Maccaferri et al., 2011; Mukhamediev et al., 2017; Rivalta et al., 2015), and is similar to that observed in analog experiments (Daniels & Menand, 2015; Urbani et al., 2017). However, it must be stated that teardrop geometries obtained in experiments are observed in a dynamic system, while the modeling results presented in this paper refer to a solidified system.…”
