Simplified 'age plotting' workflow

ODM3 version 3.7 adopts a simplified approach to handling the time elements of chronostratigraphic-based data. Users can now correlate in age to create stratigraphic summary charts (or Wheeler diagrams) that more accurately represent depositional and non-depositional systems in space and time.

Based on user feedback we have made the following improvements:

New 'age-depth mapping' data type

Age data is now stored in a new ‘depth/age mapping’ data type, which records the relationship between depth and age. This can be auto-populated as part of the stratigraphic scheme functionality (where the scheme automatically builds this as part of the interpretation process) or can be imported and manually manipulated.

It is now possible to store more than one version of the age-depth mapping (e.g. different interpretations of the biostratigraphy). Each will be stored in a unique data type, set up as 'depth/age mapping', and when it comes to displaying the wellstick in age you can specify which to use.

Improved representation of inter-well geology

Chronostratigraphic correlations (or Wheeler diagrams) now display more accurate representation of inter-well geology, due to the enhanced handling of age data. Users can choose to reshape ties to represent hiatuses (erosional or non-depositional events).

More information can be found in the attached document, which contains screen shots to demonstrate how these new features work.
