Spatial and Temporal Evolution of Graben Formation During Rift Linkage Using Quantitative Geomorphology: Insights From Central Afar

Reha Chandresh, Alexander C. Whittaker, Rebecca Bell, Giacomo Corti et autres

Abstract Quantifying fault slip rates and resolving rift segment linkage mechanisms is important for understanding the evolution of magma‐rich rift systems and the broader processes of continental break‐up. In tectonically and volcanically active rifts, such as Afar, there is commonly a lack …

Cluster analysis reveals increasing plume-like magmatism during progressive rifting in Afar (Ethiopia)

Gianmaria Tortelli, Pierluigi Crescenzi, Carolina Pagli, Anna Gioncada et autres

Reconstructing chemical variations of magma during rifting is challenging due to the heterogeneous mantle sources of the melt and different evolution pathways that magma potentially takes. Therefore, how and when the magma generation process evolves to that typical of an oceanic ridge …

Cross-scale strain analysis in the Afar rift (East Africa) from automatic fault mapping and geodesy

Alessandro La Rosa, Pauline Gayrin, Sascha Brune, Carolina Pagli et autres

The formation of continental rift systems is characterised by the interplay of magmatic and tectonic processes. Their evolution involves a wide range of timescales, from centennial scales of the seismic and diking cycles to strain localisation during millions of years of continental …

Volcanism records plate thinning driven rift localization in Afar (Ethiopia) since 2-2.5 million years ago

Gianmaria Tortelli, Anna Gioncada, Carolina Pagli, Dan N. Barfod et autres

Abstract Magma-rich continental rifting and breakup commonly show complex distributions of volcanism, potentially due to both plume and rifting controls. As such, interpreting the main controls on the spatial evolution of magmatism is debated, as is the point at which continental rifting …

Combined automatic fault mapping and geodesy to investigate the spatial and temporal evolution of tectonic strain across time scales: an application to the Afar rift (East Africa)

Alessandro La Rosa, Pauline Gayrin, Sascha Brune, Carolina Pagli et autres

Continental rift systems are characterised by spatial and temporal changes in the style (distributed vs. focused), location and mechanisms (magmatic vs. tectonic) of plate spreading. Understanding the long-term evolution of continental rift systems thus requires investigation of magmatic and tectonic processes across …

Fault Evolution in Magma-Rich Rifts using Quantitative Geomorphology: Insights from Central Afar, Ethiopia

Reha Chandresh, Derek Keir, Alexander C. Whittaker, Giacomo Corti et autres

A major challenge in magma-rich continental rifts, such as Afar, is to understand the evolution of fault networks in space and time. This is due to the lack of subsurface seismic reflection data and the presence of complex, variable-age lava flows at …

From melt- to crystal-rich magmatic systems during rift localization: Insights from mineral chemistry in Central Afar (Ethiopia)

Gianmaria Tortelli, Anna Gioncada, Carolina Pagli, Eleonora Braschi et autres

Abstract Magmatism plays a key role in accommodating and localizing extension during continental breakup. However, how the crustal magmatic systems evolve at the continental-ocean transition is poorly understood. We address these questions by studying the evolution of the magmatic system in the …
