The ocean is made up of layers. The topmost area, which receives the most sunlight, has the warmest temperatures. Each layer below the surface becomes incrementally cooler the deeper you go. Answer and Explanation: Learn more about this topic: ...
The thermochemical structure of lithospheric and asthenospheric mantle exert primary controls on surface topography and volcanic activity. Volcanic rock compositions and mantle seismic velocities provide indirect observations of this structure. Here, we compile and analyze a global database of the distribut...
The causes of magmatism at magmatic rifted margins and large igneous provinces (LIPs) are uncertain because the condition of the mantle that underlay them during formation can no longer be directly observed. Therefore, whether the mantle was characterized by elevated potential temperatures (T-P), sm...
The thickness of thermal lithosphere is also estimated assuming its bottom has a mantle adiabatic temperature of 1300掳C. Our results show that the study area exhibits an alternate distribution pattern with three weak zones and two stable blocks. The Qilian orogen, the Shanxi rift system and the...
This classical method requires specification of the mantle composition, which is usually taken to be pyrolite (Ringwood, 1962). Well-defined discontinuities at depths of 410 and 660 km have been linked to the olivine–wadsleyite transition and to the dissociation of spinel to ferropericlase and ...

mantle is demonstrated; it utilizes the best set of experimental data for rocks, namely, their densities, directly determined to pressures and temperatures comparable to those in the lower mantle, together with the most dependable properties of the lower mantle: its seismic velocities and its ...
Interaction between crust and weakening lithospheric mantle: Taking the Yanshan orogenic belt as an example Four-period calc-alkaline volcanic rocks are widespread in the Yanshan erogenic belt. The components of magma sources were controlled predominantly by the ... FX Lu,JP Zheng,RS Zhang,... ...
