Some Radiocarbon Dates for Tufas of the Craven District of Yorkshire
14 C dates of relict tufa deposits at Gordale indicated a Subboreal age when the carbonate age was corrected with empirical bedrock dilution factors ‘q’ of 0.79 or 0.85. Estimates of ‘apparent age,’ based on extrapolated δ 13 C values were about twice those obtained with q, and the 1 σ error was large. The δ 13 C values of tufa samples were not correlated with carbonate age and were close to −10. Application of q values in this district requires …
Hydrological Implications from 14 C Profiling of UK Tufa
Tufa is a superficial, secondary deposit of calcium carbonate which accumulates on precipitation from emergent spring waters. It occurs as discrete, localized masses in regions of calcareous country rock. In the United Kingdom, deposits vary widely in structure and thickness but little is known of the rate of deposition. Some deposits contain laminae assumed to represent annual growth increments and which should contain a 14 C and stable isotope …
