The rock chosen for this aquaculture site originates from southeast Florida. This limestone is part of the Bryozoan facies of the Miami Limestone. This rock is characterized as a white to yellowish granular limestone. Occurrences of iron staining on the rock are common and variable. The rock is a biosparite according to Folk’s classification of carbonate rocks. It is well lithified but may be somewhat friable on the surface, due to the matrix of oolitic sand. The rock is fossiliferous with large tubular branches of bryozoans crisscrossed within the rock. These bryozoan branches are in a matrix of oolitic carbonate sand with abundant juvenile pelecypod molds. The natural porosity of this rock has resulted in its forming one of the more transmissive aquifers in the State of Florida.The flow of groundwater through the rock has caused significant recrystallization and weathering of the rock, as well as replacement of the fossil shell material. Calcite crystal and large voids have resulted. The natural porosity, lightweight, and aesthetic look of the Miami Limestone, Bryozoan Facies, make this rock well suited for aquaculture base rock. It's irregular surface and well-developed lithification will reduce the mobility of the rock placed on the sea floor.The Miami Limestone, Bryzoan Facies has no counterpart paleontologically anywhere else in the world except in the Bahamas Platform. This will make identification of this rock on the West Florida Shelf very easy. There are no natural occurrences of oolitic carbonate sands in this area.
