URANIUM SERIES DATING: SOUTH FLORIDA FINDINGS

Time: 7:00 pm til 8:00 pm

Location: Deering Estate Auditorium, 16701 S.W.72th Ave., Miami.

Description: How do archaeologists and geologists find the age of found artifacts and materials? One method is Uranium series dating (USDD). This method has been successfully applied to corals, travertine, eggshell, tooth enamel, and wood, but less successfully to oyster shell, peat, cementum, dentine, and bone. In Florida the abundance of carbonates, flora, and fauna in close association provides opportunities for studies on uranium uptake and comparative dating with Electron Spin Resonance (ESR), Optically Stimulated Luminescence (OSL), and Radiocarbon techniques
Under conditions of burial in impermeable matrix almost every type of sample can be dated. The Dade-Collier Training and Transition Airport (TNT) vertebrate locality is an example of this condition where USDD was used. During the late 1960s and early 1970s, work began on a new Dade Collier Jetport in the Everglades. During construction of the first runway (still in use today for training flights), a barrow pit was excavated to provide fill for the runway. This fill contained fossil bones and teeth of horses, camels, and proboscideans. The limestone containing the bones was set aside as it was not suitable as runway fill and othe
