Marker ages are the geological age and type assigned to each marker of a marker set. g-Space writes them to a plain, tab-separated text .txt file with three columns: Marker, Age and Type. This topic covers exporting that file; the same layout can be edited and read back with Import marker ages.

Purpose

Write the current markers of a marker set, together with their ages and types, to a text file for review, editing in a spreadsheet, or transfer to another project. Every marker in the set is exported in its stored order.

Launching the export

In the Data manager, right-click the marker set to export and choose Export markers ages.

Step-by-step

1. Right-click the marker set and select Export markers ages.
2. In the file dialog, set the filter to Text file (*.txt) and choose a name and location.
3. g-Space writes a header line followed by one line per marker, each holding the marker name, its age and its type separated by tabs.

File format

The file begins with a header line Marker column Age column Type column and then one tab-separated line per marker:

• Marker - the marker name.
• Age - the numeric age value.
• Type - integer type code: 0 = Marker, 1 = Fault, 2 = Intrusion.

The layout matches Import marker ages, so an exported file can be adjusted and re-imported. Marker ages are part of the geological interpretation license.
