After a while, we are left with layers of chemically ...
WebThe movement of the crystals is caused by friction forces between the magma and the crystals and by gravity, which leads to crystal settling. Assuming the crystals to be spherical, the settling velocity can be derived from Stokes's law which describes the friction force of a spherical particle moving with a certain velocity relative to a highly ...

The continental crust is the end product of multistage magmatic differentiation, wherein felsic liquids and mafic rocks in the form of cumulates and restites are generated. The felsic liquids segregate toward the surface and leave behind mafic rocks at depth. At high pressures, these mafic rocks stabilize garnet and pyroxene ...
