 · In summary, because most atoms in a solid chunk of metal don't have access to oxygen atoms, because metals have a high ignition temperature, and because metals are good thermal conductors, they don't burn very well in everyday situations. The ideal way to get a metal to burn is to grind it into a powder, mix in an oxidizer, contain it so heat ...

 · (b) Minerals that show major element growth zoning probably did not experience very high metamorphic temperatures. At high temperature (gt; 700 C) and sufficient duration, zoning may be homogenized as intracrystalline diffusion becomes more effective at eliminating compositional variation.

6 Metamorphic Rocks – An Introduction to Geology

Temperature measures a substance's energy—an increase in temperature represents an increase in energy. Temperature changes affect the chemical equilibrium or ion balance in minerals. At high temperatures atoms may vibrate so vigorously they jump from one position to another within the crystal lattice, which remains intact.

at high temperatures. After cooling, the material was examined by means of the petrographic microscope and by study of its Xray pattern. It was found that the betatoalpha transition of calcium sulfate occurs at approximately 1,214° C, and the conclusion of its discoverer that the high temperature form is unstable was confirmed.
