Question details

You are attempting to reconstruct local sea level history and shoreline progradation for the beach ridge

complex pictured below. Thick peats accumulate between the beach ridges (troughs called swales).

Part A

a) Identify at least 2 means of dating swales.

b) Identify at least 2 means of dating ridges.

Part B

In the next stage of your field work, you find a relic version of a beach ridge complex that is very

similar to the modern one you just investigated. However, this complex is isolated from the sea on a

marine terrace, and is ~15 m above current sea level. You think it is from the last interglacial period (>

100,000 y). What methods would you use to determine its age?
