Study Notes

Geology Overview

Geology is the scientific study of the Earth, encompassing its surface, origin, composition, structure, and inhabitants.
It integrates various branches to understand different aspects of the Earth system.

Branches of Geology

Physical Geology (Geophysics)
- Examines physical processes and properties of Earth and surrounding space.
- Utilizes quantitative methods for analytical studies.
Petrology
- Focuses on the origin, composition, distribution, and structure of rocks.
Mineralogy
- Investigates the composition and properties of minerals.
Structural Geology (Tectonic)
- Studies the three-dimensional distribution of rock units relative to their deformation histories.
Stratigraphy
- Analyzes rock layers (strats) and the processes of layering (stratification).
- Primarily applicable to sedimentary and layered volcanic rock studies.
Paleontology
- Investigates ancient life through fossils to deduce organisms' evolution and ecological interactions (paleoecology).
Crystallography
- Experimental science focused on determining atomic arrangements in crystalline solids.

Applied Geology Disciplines

Mining Geology
- Merges economic geology and mining engineering in resource development of defined mineral deposits.
Geology Engineering (Geotechnics)
- Applies scientific and engineering principles to address Earth material knowledge for engineering solutions.
Hydrology
- Studies the movement, distribution, and quality of water on Earth and other planets.
- Focuses on the hydrologic cycle, water resources, and environmental sustainability of watersheds.
