These sedimentary structures ars where the current will initially meet the ripple at the stoss and flow downwards towards the lee side. This results in sand depositing on the lee side creating an asymptotic structe preserved ripple marks of an origin of wave or current processes. Wave and current ripples can occur in different shapes and scales but are typically differentiated by their crest symmetry or laminae. These structures may either be considered as asymmetrical wave ripples or straight-crested current ripples. A cross-sectional profile of a preserved ripple would reveal its anatomical parts, such as its crest, trough, and lee and stoss sides, which can be indicative of flow direction or energy. Similar to a sinusoidal cycle, the crest represents the peak of the ripple where it reaches maximum height while the trough is the lowest point of the ripple of minimum height, which can be best exemplified by wave ripples due to oscillating wave movements resulting in dominant sand deposition on crests and more sinusoidal, symmetrical shapes. The lee and stoss indicate the front and back sides of a ripple with a directional flow; the lee representing the backside and the stoss representing the front. These are commonly seen in current ripples where the current will initially meet the ripple at the stoss and flow downwards towards the lee side. This results in sand depositing on the lee side creating an asymptotic structure of a steeper lee side and a gentler stoss side. A larger scale or a cross-sectional view of the laminae would be useful for distinction since current ripples typically have more prominent laminae revealing the contrast in inclinations of the lee and stoss sides, whereas wave ripples are typically characterized by superimposed chevron-like laminations or bifurcation of the crests.
