Use of Fischer plots to define third-order sea-level curves in Ordovician peritidal cyclic carbonates, Appalachians Available to Purchase

Fischer plots in which cumulative cycle thickness corrected for linear subsidence is plotted against time were originally used in the study of Triassic peritidal sequences to define short-duration departures in relative sea level in the Milankovitch range (10⁴ to 10⁵ yr). However, they also provide a means of assessing magnitude of third-order (1 to 10 m.y.) fluctuations in sea level which, on the basis of their regional correlatability, we ascribe to eustatic events.
