Raindrop Impressions Encyclopedia, Science News & Research Reviews Introduction Previous Next. A raindrop trail is a geological feature characterized by small crater-like holes with slightly raised edges resulting from the impact of raindrops on the surface of soft sediments. A sedimentary structure with a similar appearance has been found.5.4.7. Raindrop Impressions Mississippian raindrop impressions over wave ripples from Nova Scotia. Like their name implies, raindrop impressions are small pits or bumps found in soft sediment. While they are generally believed to be created by rainfall, they may be caused by other agents such as escaping gas bubbles. 5.4.8. ImbricationRaindrop Impressions: Raindrop impressions are small depressions on sediment surfaces caused by the impact of raindrops. They can indicate periods of intermittent wetness and can provide clues about the local climate and environment. Load Structures: Load structures, such as load casts and flame structures, are formed when denser sediments sink ...Raindrop impressions form on exposed sediment by raindrop impacts. Parting lineations are subtly aligned minerals that form in the lower part of the Upper Flow Regime within plane beds.
