Generation of sedimentary fabrics and facies by repetitive excavation and storm infilling of burrow networks, Holocene of south Florida and Caicos Platform, BWI

Sedimentary facies generated by repetitive burrow excavation and infilling commonly are massively bedded and generally are mottled skeletal packstones. Skeletal grains usually are well-preserved and coarser components are concentrated in burrow networks, pockets and patches. The coarse skeletal components of burrow-generated facies are a mixture of coarse bioclasts from the precursor facies and both the coarse and fine skeletal material introduced from the sediment surface. -from Authors
