Abundance

VolumePerVolumeMeasure

The relative abundance of the qualifier estimated based on a "visual area" by inspecting the cuttings spread out on the shaker table before washing, or in the sample tray after washing.

This represents the upper bound of the observed range, and is in the following increments at the upper bound:

1 = less than or equal to 1%

2 = greater than 1% and less than 2%

5 = greater than or equal to 2% and less than 5%

and then in 5% increments, 10 (=5-10%), 15 (=10-15%) up to 100 (=95-100%).

The end user can then elect to either display the %, or map them to an operator-specific term or coding, e.g., 1 less than or equal to 1% = rare trace, or occasional, or very sparse, etc., depending on the end users' terminology.

i.e. 1 less then or equal to 1%=Rare Trace, or occasional, or very sparse etc., depending on the the end users' terminology.)
