Varves image library

Annually laminated (i.e. varved) sediment sequences are important natural archives of paleoenvironmental conditions that offer: 

1. accurate "internal" age spacing in calendar years; 

2. exceptional high (e.g., seasonal) temporal resolution;

3. possibility to calculate influx rates.

This online Varves Image Library offers exemplary views on many different varve types in terms of field, macroscopic, microscopic and X-radiographic images from all continents. Some images are combined with analytical data and interpretations, whereas others document seasonal sub-laminae and the succession of their components. The Varves Image Library is intended to summarize and disseminate existing image information about varves and to facilitate efforts of students and scientists to get acquainted with the challenging topic of finely laminated sedimentary structures.
