WebDec 5, 2024 · Modeling of gravity data suggests the crust beneath rift segments is intruded by dense, likely mafic rock, and that the crust is thinner (e.g., Tiberi et al. 2005; Lewi et al. 2016). Some regions of the Afar Depression have already subsided below sea level, suggesting strongly that seafloor spreading is imminent in Afar (Fig. 1). WebThese localised zones of faulting and magmatism (magmatic segments) show a segmentation independent of the border fault segmentation, and are interpreted as …
