Partial melting - simple process, huge global
... Rocks are made of minerals, which all have different melting points. Minerals containing oxygen (O) and silicon (Si) have the lowest melting points, whilst minerals that contain iron (Fe) and magnesium (Mg) have the highest melting points.

History of geology
The history of geology is concerned with the development of the natural science of geology. Geology is the scientific study of the origin, history, and structure of the Earth. Throughout the ages geology provides essential theories and data that shape how society conceptualizes the Earth.
