| Prior investigations of changes in the direction of drainage and their chronology were based on ancient shorelines, varve clay counts and radiocarbon datings. |
| Thirty-six couplets were distinguished in the stratified calcareous clayey silt between 700 and 670 cm, however, varve counting in these rhythmites was aggravated. |
| Llanquihue Lake's varves are a node point in southern Chile's varve geochronology. |
| To varve, turn roast on a cut end and slice meat away from rack of bones. |
| The basal, coarse layer of a varve is commonly overlain by microlaminared silt and clay, reflecting variable streamflow during summer. |
| 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. |
