DOI: 10.1016/j.sedgeo.2016.12.001
Abstract: Abstract The Cayman Formation (Miocene), ~ 140 m thick on Grand Cayman, is incompletely dolomitized with the most of the dolomite restricted to the peripheral part of the island. These calcium-rich dolomites, with 50–60 mol%CaCO 3 (%Ca), are… read more here.
