Melting is the process in the rock cycle that causes magma to form.
Magmas form by the melting of pre-existing (parent) silicate rocks. Three major mechanisms can cause a rock to melt... these are: 1  Heating-despite being an obvious cause, this is not usually the most important cause of magmas. 2  Pressure decrease-this is a very important mechanism at divergent boundaries.agmas form by the melting of pre-existing (parent) silicate rocks.
