Stratified Rock Formation Diagram - Geological Layer Illustration #78643 (License: Personal Use)

This black-and-white engraved diagram illustrates a block of sedimentary rock with clearly defined, inclined stratigraphic layers. The layers are labeled with dip angles of 20° and 40°, demonstrating how tectonic forces tilt originally horizontal deposits. Hatching and shading techniques emphasize depth, texture, and structural orientation typical of 19th- to early 20th-century scientific illustrations.

Used in geology textbooks, museum exhibits, and educational websites to explain principles of stratigraphy, dip and strike, and deformation of rock layers; targets students, educators, and amateur geologists seeking foundational earth science visuals.
