Basic geological mapping is the fundamental process of physically observing, recording, and interpreting the distribution of rocks and structures at the Earth's surface. It transforms raw field data—like rock types, orientations, and fossil content—into a 2D representation that reveals the 3D history of a region. This "real geology" combines multiple disciplines, including petrology, structural geology, and stratigraphy, to assess everything from resource potential to environmental hazards. 🛠️ The Geologist’s Field Kit Review , historical aerial photos, and satellite data
