| Description |
English: Modern raindrop imprints in Florida, USA. (December 2008)
Raindrop imprints are scarce, but highly diagnostic, sedimentary structures. They absolutely demonstrate that a particular bedding plane was subaerially exposed - it had to be land. Raindrop imprints are expected to be small circular to subcircular pits or craters on fine-grained siliciclastic sediment surfaces. They may be associated with mudcracks and terrestrial fossils. The modern raindrop imprints shown above are in a backbeach facies having wind-rippled siliciclastic sand. The ripples are asymmetrical - formed by a 1-directional current - in this case, wind. Locality: Algiers Beach, southern shore of Sanibel Island, Gulf of Mexico coast of southwestern Florida, USA (vicinity of 26° 25' 27.64" North latitude, 82° 03' 56.17" West longitude) |
