Diagenesis in limestone-dolostone successions after 1 million years of sea level fluctuations: A case study from Grand Cayman, British West Indies.
Download2016-01-01
Meteoric diagenesis in young marine carbonate sediments has commonly been linked to fluctuations in Quaternary glacio-eustatic sea levels. The extent to which these sea-level changes are recorded in these carbonate successions, however, remains questionable. This is amply demonstrated by the...

Spatial variations in the stoichiometry and geochemistry of Miocene dolomite from Grand Cayman: Implications for the origin of island dolostone.
Download2016-01-01
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%CaCO3 (%Ca), are divided into low-calcium dolomite (LCD, %Ca < 55%) and...
