The metallogenic source material comes from the upper mantle and the lower crust.

The volcanic pipe deep to the upper mantle is the structure as a passageway for rock and ore.

Deformation events and thermal textures of the upper mantle in this region show that Fujian and the Penghu Islands are characterized by a similar rheological state of the upper mantle.

The difference of arrival times between such PS and pp waves can be used to determine the structures in the earth's crust and upper mantle.

The magnetotelluric (MT) method provides images of the electrical resistivity of the crust and upper mantle from surface measurements of natural electric and magnetic fields.

The ultramafic nodules widely distributed in Cainozoic basalt in eastern China are regarded as fragments of upper mantle that were brought up to the ground surface by basaltic magma.

Like the CORE of earth, the mantle can also be divided into two concentric layers, the lower mantle and the upper mantle.

The occurrence of pargasite reflects the participation of the upper mantle fluids and the metasomatism.

The most remarkable feature of the upper mantle is the low-velocity zone. as suggested by its name, this is a region in the upper mantle in which there is a decrease in the speed of seismic wave.

The volcanic rocks resulted from upper mantle in Mesozoic group, and volcanic rocks from lower crust in Palapene system.

The deep fracture within the sag was the path of magma upwelling, invasion, or eruption after partially melting of upper mantle.

The magma originated from the upper mantle and belongs to the tholeiitic series which has undergone immiscible separation of metal sulfide.

The results show that the crust and upper mantle structures present obvious lateral and vertical inhomogeneity.

Finally, some possible physical mechanisms, for example the Coulomb stress-triggering mechanism, the dynamic stress-triggering mechanism and the lower crust and upper mantle flow deformation mechanism, which may generate these coseismic and post-seismic anomalies, are discussed.

The local horizontal dislocation reaches about 4 km in the medium at the focal depth, where the upper mantle rises.
