Lithology Average Grades

To calculate the average grades for constant lithology:

1. Enter the name of the input file. This should be an Interval file.
2. Enter the name of the Hole ID field in Constant field 1 and the name of the lithology field in Constant field 2.
3. Set the Type to AVERAGE (or WTAVG).
4. The Character field can be FIRST or LAST.
5. Enter the name of the output file.

You can use the output file to place lithologies on any of the section type plots. The lithology will only appear once per homogeneous interval. This reduces the complexity of the output.
