The Mesopotamia anomaly (Figure A60) is located below the Zagros mountain belt at the Arabia-Eurasia plate boundary from the deep mantle up to mid-mantle and connects upward to anomaly residing in the upper mantle. In previous studies it has been … Continue reading →
The Mendocino anomaly (Figure A59) is located in the lower mantle below the northeastern Pacific Ocean, west of the North American continental margin, west of the Hudson, Hatteras and Idaho slabs and south of the North Pacific slab. It was … Continue reading →
The Mariana anomaly (Figure A57) was first shown in seismic tomography by Spakman et al. (1989) and Van der Hilst et al. (1991). In subsequent tomographic models, the Mariana anomaly, which is an steeply westward dipping, N-S trending anomaly that … Continue reading →
The Maracaibo anomaly (Figure A56) is located in the upper mantle below northern South America. It was first tomographically imaged by van der Hilst and Mann (1994), and was later recognized in tomographic models by Taboada et al. (2000), Bezada … Continue reading →
The Manila anomaly (Figure A55) is located below the northwestern Phillipine Sea in the upper mantle. The Manila anomaly dips down towards the transition zone at the base of the upper mantle and has previously been imaged in several regional … Continue reading →
The Manchuria anomaly (Figure A54), also referred to as Japan anomaly (Obayashi et al., 2009) was interpreted as a slab that dips down westward from the Japan subduction zone at surface, drapes the transition zone below east Asia and penetrated … Continue reading →
The Malpelo anomaly (Figure A53) is located below the western Panama Basin and NW South America in the mid-mantle. It is NW-SE trending and above 1175 km it is close to the Venezuela slab to the east as well as … Continue reading →
The Maldives anomaly (Figure A52) is located below the northwestern Indian Ocean from the deep mantle up to the upper part of the lower mantle. In previous tomographic studies it has been referred to as the eastern part of the … Continue reading →
The Lougheed anomaly (Figure A51) is located below northernmost North America within the mid-mantle. It is N-S to NNW-SSE trending and at its southern end lies close to, but is separate from the NW-SE trending Hudson slab that is correlated … Continue reading →
The Lake Eyre anomaly (Figure A50) was defined by Schellart and Spakman (2015). It is located at 800-1200 km depth in the upper part of the lower mantle below southern Australia. There is no record of Mesozoic or Cenozoic subduction … Continue reading →
