the seismic signature of chemical differentiation that helps mapping chemical heterogeneity in the upper mantle. The relation between chemical differentiation and its seismological signature is not straightforward because a large number of unknown parameters are involved although the seismological observations provide only a few parameters (e.g., VP, VS, QP). Therefore it is critical to identify a small number of parameters by which the gross trend of chemical evolution can be described. The variation in major element composition in natural samples reflect complicated processes that include not only partial melting but also other complex processes (e.g., metasomatism, influx melting). We investigate the seismic velocities of hypothetical but well-defined simple chemical differentiation processes (e.g., partial melting of various pressure conditions, addition of Si-rich melt or fluid), which cover the chemical variation of the natural mantle peridotites with various tectonic settings (mid ocean ridge, island arc and continent).

What is the change in structure and function of a cell as it matures: specialization Answer: differentiation
Stem cells are necessary for cellular differentiation because when they divide, they become specialized cells.
differentiation
This is broadly known as planetary differentiation.
chemical modifications of histones and DNA methylation.
differentiation.
It is not possible because we need a differentiation between elements, including different chemical symbols.
