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.
