The Reggane anomaly (Figure A71) is a small anomaly located in the upper part of the lower mantle below the western Sahara in the lower mantle and is resolved in both the UUP07 and S40RTS models. It was previously identified … Continue reading →
The Papua anomaly (Figure A70) corresponds to the northern part of the A7 anomaly of Hall and Spakman (2002; 2004) and underlies an area from Papua New Guinea to the New Hebrides and from the east Australian margin to the … Continue reading →
Subduction in the Pamir (Figure A69) was first demonstrated by Burtman and Molnar (1993), and became evident from deep seismicity down to 250 km depth (Pegler and Das, 1998; Pavlis and Das, 2000; Koulakov, 2011; Zhang et al., 2011; Schneider … Continue reading →
The North Apennines anomaly (Figure A67) is located below Corsica and Tuscany in the upper mantle. Based on early tomographic models, Spakman et al. (1993) interpreted the North Apennines anomaly as a detached slab, but subsequent models rather suggested that … Continue reading →
The New Hebrides anomaly (Figure A66) is located west of the northern termination of the Tonga trench, and is interpreted as lithosphere still subducting at the New Hebrides subduction zone. It is a NW-SE trending slab that was imaged before … Continue reading →
The New Britain anomaly (Figure A65) corresponds to anomaly A3 of Hall and Spakman (2002; 2004) and was previously imaged by Bijwaard et al. (1998). It is an E-W trending anomaly interpreted as a slab that reaches the base of … Continue reading →
The Nepal anomaly (Figure A64) is located in the lower mantle below the Himalaya. Its position south of the shallower part of the Mongol-Kazakh slab and north of the deeper part of the India slab suggests that the Nepal anomaly … Continue reading →
The Mongol-Kazakh anomaly (Figure A63) is located below northern Siberia from the core-mantle boundary up to the mid-mantle. The anomaly is widely known in the literature as the Mongol-Okhotsk anomaly (van der Voo et al., 1999a) and is interpreted to … Continue reading →
The Mongolia anomaly (Figure A62) is located below northeast Asia within the mid-mantle. In previous studies it was interpreted as a Pacific slab (Van der Voo et al., 1999a). In van der Meer et al. (2010), we used the Kamchatka-Kuriles … Continue reading →
The Missisippi anomaly (Figure A61) is part of the set of anomalies commonly, and in our previous compilation in van der Meer et al. (2010), interpreted as the Farallon slab as originally defined by Grand et al. (1997). The NW-SE … Continue reading →
