The late-Holocene tufa decline in Europe
Over much of Europe, it has been postulated that in the late Holocene (since c.2500 BP) there was a marked decline in the deposition of tufa. There has been considerable debate about the causes of this phenomenon, with some authors postulating the importance of natural climatic changes, and others asserting that miscellaneous human influences have been crucial. This article discusses the role that various changes, both natural and anthropogenic, …
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 …
