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 current energy crisis has generated an increased interest in alternate source of energy. Resources such as geothermal, solar, and ocean thermal are being actively considered for wide-spread development in the United States and many other countries throughout the world.
