Melting Points of Rocks and Minerals

It is impossible to determine melting temps for micas, amphiboles and any other mineral that contains water - because hydrous minerals break down via dehydration reactions before they melt. And, we really cannot determine melting temperatures for minerals like quartz and Kspar because they change into different minerals when heated, before they melt, even though they do not contain water.
