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.
