Raindrop impressions.

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.Raindrop impressions form on muddy surfaces. Horizontal strata occur where sediments settle from water or air; or where air or water currents move parallel to the surface on which sediments are accumulating. Current ripple marks occur in any environment where wind or water currents move in only one direction for a period of time: wind blownMar 28, 2012 · Now University of Washington researchers, using evidence from 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.
