varvechronology
Varvechronology is a dating method used in geology and archaeology to establish a chronological record of past events. It relies on the analysis of varves, which are annual layers of sediment deposited in bodies of water such as lakes or glaciers. These layers typically consist of two distinct parts: a lighter-colored, coarser layer deposited during the spring and summer melt season when sediment is abundant, and a darker-colored, finer layer deposited during the fall and winter when meltwater and sediment supply are reduced.
The thickness and composition of each varve can vary depending on environmental conditions such as temperature,
Cross-dating, a technique where varve sequences from different locations are compared and matched based on their
