It has long been realized that the mineral assemblages of igneous and metamorphic rocks may reflect the approach of a rock to chemical equilibrium during its formation. However progress in the application of chemical thermodynamics to geological systems has been hindered since the time of bowen and the other early physical-chemical petrologysts by the recurring quandary of the experimental geol…
The science of geology is concerned with the earth and the rocks of which it is composed, the processes by which they were formed during geological time, and the modelling of the earth’s surface in the past and at the present day. The earth is not a static body, but is constantly subject to changes both at its surface and at deeper levels.
