densitystructureThe Emeishan large igneous province(hereafter named by its acronym ELIP)is the first accepted large igneous region in China.The current study tries to reconstruct the density structure of the crust in this region.For this purpose,we conducted the gravity survey along an 800-km-long...
[#insert4]Wegener maintained that Earth is composed of concentric shells of increasing density from crust to core. The outermost shell is not continuous but made of continental blocks of lighter rock called sial (an acronym for silica- and aluminum-rich rock) floating in the denser sima (...
These constraints record the intense crust–mantle interaction in the southern margin of the NCC. Given the regional data and spatial distribution of Early Cretaceous rocks within NCC, we believe that the formation of these rocks is related to the contemporaneous far-field effect of the Paleo-...
Continental crust is made up of many different types of igneous, metamorphic, and sedimentary rocks. The average composition is granite, which is much less dense than the mafic rocks of the oceanic crust (Figure 3). Because it is thick and has relatively low density, continental crust rises ...
The stress redistribution along the brittle, velocity-weakening, part of the crust triggers the occurrence of other earthquakes, the aftershocks. They follow well established empirical laws that can be put in the form of power laws with quite universal values for the exponents2. In particular, ...

Which layer of Earth has the highest density and temperature? How much copper is in the Earth's crust? Where is the Earth's crust the thinnest? How did the Earth's crust form? What are the characteristics of the Earth's crust, mantle, and core?
This low-density crust acted as a barrier for the dense primary mantle melts. This is particularly evident in the fact that subsequent mare basalts erupted primarily within large impact basins: at least part of the crust must have been removed for the magma to reach the surface. However, the...
how much pressure may be put upon water its volume is little decreased and its density little changed. So it happens that substances which readily sink in the upper part of the sea sink to the bottom no matter how deep the water may be, as the bottom is so little denser than the top...
