Structural geology is the study of the three dimensional distribution of large bodies of rock, their surfaces, and the composition of their inside in order to try and learn about their tectonic history, past geological environments and events that could have changed or deformed them. These can be dated to determine when the structural features formed.

If the nature of these rocks can be determined, petroleum geologists can discover if petroleum, natural gas, or other natural resources are trapped within the rocks.
