Definition TheMoho, an abbreviation of the termMohorovicic discontinuity, is the boundary between the Earth’s crust and themantle. Identified first as a seismic reflector, where a marked change in the velocity of seismic waves reflects a change in rock type from low-density rocks of the crust ...
FromNew York Times He had discovered the boundary between the crust and the layer immediately below, the mantle; this zone has been known ever since as the Mohorovičić discontinuity, or Moho for short. FromLiterature And after that, he and his colleagues hope to use the Japanese drill sh...
The Curie isotherm generally lies above the Moho in this region but deepens into the mantle in some locations, notably beneath the Asir Terrane. " 展开 关键词: Curie depth Magnetic anomalies Moho depth Magnetization Saudi Arabia Arabian shield ...
(1992) suggested that the lower crust and upper mantle may have similar magnetic properties, effectively removing the Moho as a magnetic discontinuity. Trifonova et al. (2009) estimated the CIS for Bulgaria using magnetic data and concluded that the Moho lies at depths of approximately 30km, ...
The seismic Moho is defined as a first-order velocity discontinuity where P-wave velocities increase abruptly from crustal values (<7.2 km s−1) to mantle values (>8.0 km s−1) (Rohr et al., 1988, Holbrook et al., 1992). The seismic Moho may not correspond to the petrologic ...

Therefore, we suggest that the transition between relatively thick and thin MTZ at the horizontal distance of 30–40 km at ∼9°35′−9°41′N could be associated with the third-order tectonic (and chemical) discontinuity at 9°37′N (Fig. 1). These interpretations are supported by ...
