The diagram above illustrates an important point for both the melting of mantle rocks and the crystallization of high temperature silicate liquids (magma or lava).
图表上方举例说明地涵岩石和高的温度矽酸盐液体（岩浆或熔岩） 的结晶的两者熔化者的重要的点。

All magma consists basically of a variety of silicate minerals, high in silicon-oxygen compounds, but the chemical composition of any given flow may differ radically from that of any other.
