Buck (1991) aims at solving the intense ‘70s and ‘80s tectonic debate concerning the way extension is accommodated in continental regions (see our previous blog posts here and here). His article explores the physical conditions that can lead to the three end-member modes of lithospheric extension in continents: core complex mode, wide rift mode and narrow rift mode. The three extensional modes th ...[Read More]
Lister and Davis (1989) is a seminal article for core complexes and detachment faults, cited well over a thousand times. The authors describe geometry and kinematics of core complexes, cropping out in the USA, which result from lithosphere extension. The paper carefully describes the main detachment fault separating lower plate from upper extending plate and discusses the role of granitoid intrusi ...[Read More]
Continental extension strongly affects the topography of continents by shaping elongated rift valleys, referred to as rift basins in the geological record. A strong implication of the formation of these basins is a two-step subsidence history: an initial rapid subsidence during extension, and a second, slower subsidence once active extension has ceased. Although this observation was made already l ...[Read More]
