| These sediments, called varved clays or simply varves, are the primary habitat of Axarus larvae. |
|
| Some investigators believe the laminated clays are varves and that each couplet represents one year of seasonal deposition. |
|
| It is impossible to create an accurate calibration curve based on the varves if you do not know precisely how big the gaps in the soil are. |
|
| The thickness of varves is variable, depending on the cyclicity of sedimentation. |
|
| The varves represent a year of the lake's history: a pale coloured layer of silty sand deposited in summer, and a dark clay layer deposited in winter. |
|
| Llanquihue Lake's varves are a node point in southern Chile's varve geochronology. |
|
| The couplet data are not considered to provide an exact representation of the age of the unit as some couplets may not be true varves. |
|
| The lack of disturbance allows for the development of lacustrine varves. |
|
| Varves are a common feature in many areas and especially so where the land has received meltwaters from ice sheets and glaciers. |
|
| Varves afford geologists an opportunity to calculate the age of the lake, similar to counting the rings of a tree trunk. |
|
| Varves form a sedimentary bed or lamina or sequence of laminae deposited in a body of still water within one year's time. |
|
| Varves arise in response to seasonal changes. |
