Process of Obduction in Global Mantle Convection ModelsM. UlvrovaN. ColticeP. Tackley
In the process of plate tectonics, which reflects the correct relationship between the asthenosphere (a part of the upper mantle) and the lithosphere? A. The asthenosphere is a rigid layer that restrains the movement of the lithosphere B. The lithosphere floats on the asthenosphere and is ...
Plates reorganization associated with mantle convection leadsto changes in absolute plate velocities which may in turn impactthe geometry of slabs and the upper plate regime of deformation.Analogue experiments suggest a very good correla... S Hertgen,B Guillaume,J Martinod 被引量: 0发表: 2016年...
When two plates are rubbed against each other and one plate is melted in the mantle, it can cause geologic activities. Some examples are earthquakes and the formation of volcanoes. When lithosphere melts into magma, it forms volcanoes in a line along the subduction zone. Continental subduction ...
The mantle-derived ultramafic host rocks must be exposed to the surface for extensive physical and chemical weathering for metal enrichment through thesupergene process. 2. A stable paleoclimate is one of the major controls on formation of nickel laterite deposits. A comparison of climatic data cond...

First, the lithospheric mantle keel was partially removal by mantle convection at 145 Ma. Loss of the lower lithosphere would increase heat flow into the base of the crust and would cause middle-lower crustal melting. Second, partial melting of the thickened lower crust has weakened the lower ...

Zircon U-Pb ages and different compositional trends for the two series indicate that the lithospheric mantle keel was partially removed by small-scale mantle convection that triggered the Late Cretaceous high-Mg-# adakitic magmatism in the Lhasa-Qiangtang collisional orogen. Partial lithospheric ...
