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.
key features of holostratigraphy reports are:
- All information is summarised in, and accessible from, a single
- The holostratigraphy table summarises data on lithostratigraphy,
chronostratigraphy, biostratigraphy, sequence stratigraphy, magnetostratigraphy,
- 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
- show how new research relates to previous work
- constitute a focus for future research.
