Definition of varve in English:

varve

noun vɑːvˈvärv

Geology

A pair of thin layers of clay and silt of contrasting colour and texture which represent the deposit of a single year (summer and winter) in a lake. Such layers can be measured to determine the chronology of glacial sediments.
〔地质〕季候泥，纹泥；（季候泥，纹泥）年层
Example sentencesExamples
- The basal, coarse layer of a varve is commonly overlain by microlaminared silt and clay, reflecting variable streamflow during summer.
- Some investigators believe the laminated clays are varves and that each couplet represents one year of seasonal deposition.
- Analysis of varves (banded sediments in lakes that show annual variation) can be used to date Pleistocene sediments.
- Each summer/winter pair of layers - called varves - would thus represent a single year.
- These sediments, called varved clays or simply varves, are the primary habitat of Axarus larvae.

Derivatives

varved

adjective

Geology

Silt and varved clay, probably deposited during the last stages of Pleistocene glaciation, cover the entire floor.
Example sentencesExamples
- Axarus larvae almost always infest varved clay deposits that are remnants of Pleistocene glacial lakes.
- Sediments in many proglacial lakes are varved (annually laminated) and thus offer the same temporal resolution as trees for paleoenvironmental studies.
- In glacial terrains coarse-grained, so-called Gilbert-type deltas of gravels and sands are common, and these pass in deeper water into varved sediments.
- We have obtained and analyzed cores of varved sediments from Cheakamus, Green, and Glacier lakes.

Origin

Early 20th century; from Swedish varv 'layer'.
