Editing Varve (section)

==Etymology==
The word 'varve' derives from the [[Swedish language|Swedish]] word ''varv'' whose meanings and connotations include 'revolution', 'in layers', and 'circle'. The term first appeared as ''Hvarfig lera'' (varved clay) on the first map produced by the [[Geological Survey of Sweden]] in 1862.<ref>{{Cite journal  |pages  = 3105–3114  |last = Zolitschka |first = B. |title = Varved lake sediments |journal = Encyclopedia of Quaternary Science |date = 2007  |url = http://www.climategeology.ethz.ch/education/limnogeology/Zolitschka_2007.pdf |access-date  = 2014-03-19 |archive-url = https://web.archive.org/web/20150922035619/http://www.climategeology.ethz.ch/education/limnogeology/Zolitschka_2007.pdf |archive-date = 2015-09-22  |url-status = dead}}</ref>
Initially, "varve" referred to each of the separate components comprising a single annual layer in [[glacial lake]] [[sediment]]s, but at the 1910 Geological Congress, the Swedish geologist [[Gerard De Geer]] (1858–1943) proposed a new formal definition, where varve means the whole of any annual sedimentary layer.<ref>De Geer, G.
