Molluscan carbonate, present as snail or clam shells in lacustrine sediments, appears to give less reliable ages. Bone, although containing the highest U- series dates of marine, biogenic carbonates have been used to establish high sea-stands related to eustatic fluctuations. Low sea-stands can be established by dating. Title: Uranium-series Dating of Marine and Lacustrine Carbonates. Authors: Edwards, R. L.. Publication: Reviews in Mineralogy and Geochemistry, vol. 52, issue 1, pp. Publication Date: 01/ Origin: CROSSREF. DOI: / Bibliographic Code: RvMG E. 1 Jan HISTORICAL CONSIDERATIONS. Of the possible uranium-series dating schemes, the most important and most widely applied to marine carbonates is Th dating, with Pa dating playing an increasingly important role. For this reason, this review will focus on these two methods. Th dating, also.

Precise chronology of the last interglacial period — UTh data from fossil coral reefs in the Bahamas. A situation in which the quantity of a radioactive isotope remains constant because its production rate due to decay of a parent isotope is equal to its decay rate.

Several hundred Rn-Ra analyses and close to a hundred isotopic ratios were measured. The travertines may have been porous at the time of deposition, and subsequent filling of pores by later carbonate can result in spuriously young ages. U-series dating of diagenetically altered fossil corals.
