Sedimentary structures in sand beds,lacquer profile. Cross section of sand and gravel deposited during the Holocene period (11,400 years ago to the present day). Since the sediment was deposited in a shallow marine environment,there are intricate cross-bedding patterns caused by changes in flow direction and ripples. A lacquer profile is created by immersing a vertical rock section inlacquer,which is then removed after hardening to reveal patterns and textures in the rock.The section measures over 1 metre high | |
