They made the same claims with the same example in a subsequent, virtually identical, presentation in a widely circulated Christian journal (Davidson and Wolgemuth 2012).
Such results pose a serious challenge to uniformitarian assumptions underlying conventional radiocarbon age-dating methods. But what if the deposition has long ceased, and a succession of varves has been buried and lithified? This question has various answers, depending on what sort of varves we're looking at. those found in a proglacial lake, the appearance of the sedimentary couplets is quite distinctive, and we may be fortunate enough to find striated dropstones, unambiguous evidence of a glacial depositional environment. However, as we have pointed out, such ancient varves would usually not allow us to carry out absolute dating in any case, because they would have lost their link with the present: by counting varves we could determine the time interval between any two of them, but not the age of either of them.The Varves Working Group was active under the PAGES umbrella from 2009 to 2015.In many studies, the varve chronology of lacustrine and marine sediments form a solid basis for dating, not to mention the environmental and climate signal stored in varves and laminae they contain.The Varves Working Group took the steps forward to gather the varve community together again to summarize what had been accomplished during the previous years and to exchange new ideas and promote their use in global climate reconstructions.
