Because each year’s sediment accumulation varies in thickness according to the climatic conditions of the melt season, any long sequence of varve measurements provides a distinctive...
A varve is an annual layer of sediment or sedimentary rock.
The term “varve sequence” is used as a generic term to refer to any succession of varves regardless of whether they are single outcrop records or represent larger, more regional correlations involving many varve records.
Varve record: A measured string of varves from a single exposure or drill core.
The advantage that varves have over other sediments is that they have tremendous precision of a year and in some cases down to the level of seasonal layers within a varve if intra-annual stratigraphy shows a consistent separation of seasonal features.
Correlation of glacial varve records from place to place is generally based on the matching of the pattern of varve thickness change and not absolute thickness, which varies widely for a single varve year across a lake or region.
Time chronology varve dating to make the leap into the role this what does varve analysis dating mean show would be quick failure attempt. Tied to European Climatic Sequence through pollen analysis of the sediments. BIOLOGICAL: discontinuous, deposited only when activity of bottom-dwelling organisms is suppressed (anoxia), interrupted by layers of homogenized sediment, layers often indistinct, layers thin, hard to count. Rockies (Wait, 1984) varved sediments used to date floods in glacially-dammed lakes.Of the many rhythmites in the geological record, varves are one of the most important and illuminating in studies of past climate change.Varves are amongst the smallest-scale events recognised in stratigraphy.
