Stratified Rock Formation Diagram - Geological Layer Analysis #15222 (License: Personal Use)

This black-and-white engraved illustration depicts a tilted sedimentary rock sample, highlighting parallel layering (stratification), cleavage lines, and a contrasting porous inclusion likely representing a fossiliferous or cemented zone. Annotations 'a' and 'b' mark key structural features-possibly primary bedding and secondary fractures-common in field geology sketches from the late 1800s. The fine hatching technique conveys texture and dip angle, aiding in visual interpretation of depositional history.

Used in educational geology resources, museum exhibits, or digital archives to explain sedimentary structures, rock deformation, and historical scientific illustration methods; targets students, educators, and amateur geologists seeking foundational stratigraphy knowledge.
