WebPeloids are grains of indeterminate origin. They are sand or silt-size and usually subangular in shape, though often they are rounded and resemble fecal pellets. Peloids retain no internal structures to identify their origins, which are probably diverse and include micritization of grains by boring algae and fungi (right figure). WebJul 11, 2024 · Overall, Florida's geological history has been driven by changing sea levels, which have influenced the production of carbonate bedrock, siliciclastic input/transport, hydrology, and surface topography.
