Biostratigraphy image

Holostratigraphy is the integration of a wide range of geological data about particular geological intervals into a single accessible format. Holostratigraphy reports are published in PDF format, and use digital technology to arrange geological information in a way that allows the user to see how diverse subject matter is inter-related.

The key features of holostratigraphy reports are:

  • All information is summarised in, and accessible from, a single holostratigraphy table
  • The holostratigraphy table summarises data on lithostratigraphy, chronostratigraphy, biostratigraphy, sequence stratigraphy, magnetostratigraphy, chemostratigraphy, etc.
  • Historical data are shown alongside recent work. The reports are not attempts to provide definitive interpretations, but by showing new and old interpretations alongside each other, they give a greater appreciation of how stratigraphical data have evolved
  • Sequentially numbered holostratigraphy events in the holostratigraphy table have hypertext links to specific information about geological data that is useful for correlation (e.g. lithological marker-beds, fossil marker-beds, isotope excursions).

The main aims of the reports are to:

  • provide a single foundation reference source about geological intervals for established specialists and those wanting to develop new expertise
  • show how new research relates to previous work
  • constitute a focus for future research.
