This environment (which gets periodically wetted and dried) is a great one for mudcracks and raindrop marks to form. Lake interiors: the energy is very very low in the bottoms of the middle of lakes, so fine muds such as clays are the only important sediment type. With low energy the ...

fossilized raindrop impressions from 2.7 billion years ago to deduce atmospheric pressure at the time, have demonstrated that an abundance of greenhouse gases most likely caused the warm temperatures.

1 Introduction. Observing marks of a brief rain shower on the beach or on mud is a common experience to many of us. Some of these rain imprints may even have been preserved over geological time scales and are discovered as sedimentary structures that were first reported back in 1839 and are known as raindrop impressions (Cunningham Reference Cunningham 1839).

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. ImbricationThe sizes of raindrop impressions depend on raindrop velocity, the atmospheric pressure and the composition of material into which the raindrops fall.

Raindrops may make pits in soft sediments; the shape of the minute rim around the pit may indicate the direction from which the rain came. Casts of salt crystals. When salty mud dries, its surface becomes more or less covered with crystals of halite. Many of these crystals are ...

The raindrop impressions are usually found in fine-grained rocks like siltstones and shale but not in coarser-grained sandstones (Ma, Y. et al. (2018)). The impressions likely represent the end of a rainstorm as rain is letting up because any previously formed impressions would be destroyed by subsequent rainfall.

The impressions likely represent the end of a rainstorm as rain is letting up because any previously formed impressions would be destroyed by subsequent rainfall. That’s why most raindrop impressions are very scattered rather than occurring all over the surface.
