Seagrass Meadows As A Globally Signiﬁcant Carbonate
i. mazarrasa et al.: seagrass meadows as a globally signiﬁcant carbonate reservoir 1 introduction calcium carbonate (caco3) accounts for about a 25% of the surface marine sediments (balch et al., ). contemporary oceanic carbonate sediments are mainly composed of two main mineral forms of calcium carbonate, calcite.Apr 14, the miami limestone occurs in the southern part of main florida and in the southernmost keys. it consists of two layers, an oolitic facies and a bryozoan facies.the oolitic facies is located near the atlantic coast (think miami), as ooids require energy to form. the bryozoan facies, which only occurs on the florida main, is located more centrally (think everglades) because bryozoans prefer.
