The basal, coarse layer of a varve is commonly overlain by microlaminared silt and clay, reflecting variable streamflow during summer. |

In Sweden, by contrast, it has been possible to tie a glacial varve chronology to present time, and so create a truly absolute dating technique. |

Cosmogenic-nuclide and varve chronologies for the deglaciation of southern New England. |

Each annual layer, known as a varve, contains organic evidence of the earth's climate and ocean temperatures for the year it was deposited, Briskin says. |

Thirty-six couplets were distinguished in the stratified calcareous clayey silt between 700 and 670 cm, however, varve counting in these rhythmites was aggravated. |
|
We do not have this in earlier periods and so we must use other methods, the main ones being varve counting, ice-core timescales and uranium series dating. |
|
Prior investigations of changes in the direction of drainage and their chronology were based on ancient shorelines, varve clay counts and radiocarbon datings. |
