The late-Holocene tufa decline in Europe

Abstract
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, may have played, and suggests ways in which the large number of possible hypotheses can be tested.
