Petrography

Petrography is the branch of geology that focuses on the detailed study of rocks and their minerals. It involves examining the physical and chemical properties of rocks, often using a microscope to analyze thin slices of rock. This helps scientists understand the formation processes, history, and composition of different types of rocks, such as igneous, sedimentary, and metamorphic. Petrography plays a crucial role in fields like archaeology, environmental science, and natural resource exploration by providing insights into the Earth’s structure and the materials it contains.
