Orbital Time Scales: Proxies | Models | Coverage

This page is currently under development.

See DEMOS Laboratory for a screenshot demonstration of planned tools.

Proxies

      Chemical stratigraphy - isotopes (e.g., stable isotope ratios); elements (e.g., biogenic silica, carbonate, TOC, etc.)
      Physical stratigraphy - facies variations (e.g., subtidal-supratidal carbonate cycles); dust content; clay mineralogy; grain size changes; geophysical log parameters
      Magnetic stratigraphy - Susceptibility
      Biostratigraphy - cold/warm N. pachyderma coiling ratios; microfaunal/floral assemblage variations
