Objective:
|
Lower end of depth transect; lower to upper Eocene and possible Eocene/Oligocene boundary (the entire section of Eocene strata is ~400 m thick at this site, with another 350 m of Cretaceous–early Paleogene); early Eocene warm period; Eocene hyperthermals; middle and late Eocene impacts; transition to icehouse climate; Eocene CCD; chemistry of Eocene deep water. Thinning of Eocene section from JA-7 suggests the site is within the Eocene lysocline but still has a respectable Eocene sediment cover.
