What Does VPDB Stand For?

VPDB stands for Vienna Peedee Belemnite

VPDB, or Vienna Peedee Belemnite, is a standard reference material used in stable isotope geochemistry, particularly for calibrating carbon and oxygen isotope measurements. Derived from belemnite fossils from the Peedee Formation in South Carolina and processed in Vienna, it serves as a benchmark for isotopic studies, ensuring consistency and accuracy across various analytical methodologies. The VPDB scale is widely utilized in research fields such as paleoclimatology, geology, and environmental science.
