Sedimentary Rock Specimen - Geological Sample for Education & Collection #3576102 (License: Personal Use)

The specimen exhibits clear stratification and heterogeneous grain size, suggesting deposition in a fluvial or lacustrine environment; darker patches indicate organic-rich or iron-oxide-bearing layers. Its irregular surface and fracture patterns reflect post-depositional compaction and diagenesis.

Used in educational materials, museum exhibits, geology textbooks, and online rock identification guides; targets students, educators, hobbyists, and professionals seeking visual reference for sedimentary structures.
