The Sistan anomaly (Figure A81) is a N-S striking anomaly below eastern Iran and western Afghanistan in the upper part of the lower mantle. Given its orientation, its position to the west of the India slab, northeast of the Mesopotamia … Continue reading →
The Sisimut anomaly (Figure A80) is located below northernmost North America and Greenland within the mid-mantle. It is NW-SE trending and does not have a neighbouring slab in close vicinity. Van der Meer et al. (2012) suggested that the slab … Continue reading →
The Scotia anomaly (Figure A79) was first documented in the tomographic model of Bijwaard et al. (1998). It is interpreted to represent still-subducting South American plate lithosphere consumed at the South Sandwich subduction zone, and dips westward below the Scotia … Continue reading →
The Sao Francisco anomaly (Figure A78) is located below eastern South America, within the deepest mantle and resting on the core-mantle boundary. It is NE-SW trending at the core-mantle-boundary and changes to N-S trending at shallower levels. It is disconnected … Continue reading →
The San Matias anomaly (Figure A77) is located below southeastern South America, offshore Patagonia, at the top lower mantle and at the base of the upper mantle. It is a N-S trending anomaly and has previously been interpreted to have … Continue reading →
The Sangihe anomaly (Figure A76) was imaged by Widiyantoro and van der Hilst (1997), Rangin et al. (1999), and Hall and Spakman (2002; 2004) and is interpreted as one of the two actively subducting slabs attached to the Molucca Sea … Continue reading →
The Sakhalin anomaly (Figure A75) is located below northeast Asia within the upper part of the lower mantle. In previous tomographic studies it has been interpreted to as a subducted slab of the Okhotsk plate (Gorbatov et al., 2000). On … Continue reading →
The Ryukyu anomaly (Figure A74) is located in eastern Asia below the East China Sea in the upper mantle. The Ryukyu slab has previously been imaged in numerous regional and global tomographic models (Bijwaard et al. 1998; Lallemand et al., … Continue reading →
The Rockall anomaly (Figure A73) is located west of the British Isles under the eastern North Atlantic Ocean and lies on the core-mantle boundary. It was first identified in (van der Meer et al., 2010). The Mongol-Kazakh slab to the … Continue reading →
The Rio Negro anomaly (Figure A72) is located in the upper mantle below western Patagonia, southern South America. It is N-S trending and partly flat-lying. It has previously been interpreted to represent still-subducting Nazca lithosphere below the Andean margin (Aragón … Continue reading →
