Unc onf orm ity Colorado River VISHNU SCHISTS UNKAR GROUP 54 FORMATION AND TRANSFORMATION OF ROCKS ROCKS AND MINERALS 55 Metamorphic Processes 570° F hen rocks are subjected to certain conditions (high pressure and temperature or exposure to fluids with dissolved chemicals), they can undergo remarkable changes in both their mineral composition and their structure. This very slow process, called metamorphism, is a veritable transformation of the rock.
The change experienced by these substances is called carbonization. O FORMATION OF PETROLEUM 26% OF THE PRIMARY ENERGY CONSUMED IN THE WORLD COMES FROM COAL. In an anaerobic environment at a depth of about 1 mile (2 km), organic sediments that developed in environments with little oxygen turn into rocks that produce crude oil.
