Magmas erupted at mid-ocean ridges (MORB) result from decompression melting of upwelling mantle. However, the mechanism of melt transport from the source region to the surface is poorly understood. It is debated whether melt is transported through melt-filled conduits or cracks on short time scales ( 10 yrs), or whether there is a significant component of slow, equilibrium porous flow on much l...

The Zhob ophiolite is divided into Ali Khanzai, Omzha, and Naweoba blocks. geology comprises various lithological units including basalt–chert hyaloclastite mudstone units. consist of thick lava pelagic sediments. On the basis petrology geochemistry, lavas unit can be tholeiitic basalt, trachybasalt, basaltic andesite dacite, that more alkaline foidite, picrobasalt, tephrite-basanite. rocks hav...

I apply array processing techniques to study the slowness and coda of P/Pdiff for 1,371 shallow earthquakes (< 200 km) that occurred in Asia, South America, Tonga-Fiji, and Indonesia, and were recorded by the medium-aperture array, YKA, in Canada. The slowness analysis shows lateral variations in Earth structure at the base of the mantle across the north Pacific. I observe an Ultra-Low Velocity...
