Geological Fold Diagram: Understanding Rock Strata Deformation and Dip Angles #78642 (License: Personal Use)

This vintage-style scientific illustration depicts a three-dimensional fold in stratified rock, using hachures and contour lines to convey depth and layer orientation; the labeled dip angles indicate the steepness of bedding planes relative to horizontal. The shading and cross-section view help visualize how compressional stress bends sedimentary sequences, a key concept in interpreting subsurface structures in oil exploration and seismic mapping.

Used in geology textbooks, academic lectures, and online educational resources to teach structural geology concepts like folding, dip, strike, and tectonic deformation; targets students, educators, and professionals seeking visual aids for interpreting geological maps and cross-sections.
