Absence of carbon-14 activity in dolomite from Florida Bay
Deffeyes KS and Martin EL. 1962. Absence of carbon-14 activity in dolomite from Florida Bay. Science. 136(3518):782-783
A sample of dolomite crystals concentrated from Recent carbonate sediments in Florida Bay (Everglades National Park) gave a carbon-14 age greater than 35,000 years. Since Recent sedimentation in Florida Bay began less than 4000 years ago, the dolomite must be derived from older rocks, and Taft's hypothesis that dolomite is forming today is incorrect. Study Type: Quantitative; Gear Type: Surface sample; Number of Stations: 1 (Oxfoot Bank);Temporal frequency: once.
