In complete sections these hiatuses correspond to intervals of cool faunal and floral assemblages, rapid enrichment of δ18O, and sea-level regressions. These factors suggest that Miocene deep-sea hiatuses result from an increased intensity of circulation and corrosiveness of bottom currents during periods of increased polar refrigeration.
