Layered sedimentary rock with distinct bands of alternating light and dark strata. The light bands are composed of pale, chalky material, while the dark bands are thinner and appear more compact. The arrangement displays clear horizontal stratification, indicating variations in depositional environments over geologic time. The surface shows signs of weathering and minor erosion, highlighting the rock's texture and structure. This type of formation is typical in sedimentary basins and provides insight into Earth's historical geologic and environmental changes.
