The “Depth Variable” is simply the depth value.
Say you have a line log that shows Au (ppb) concentration values and you want to multiply the concentration by depth. In the Function Log dialog you would:
- Double click on Line/Symbol (the Au line log in the view) in the Log Variables list.
- Double click on * in the Operator list.
- Click the Depth Variable button. So the Function Expression is: [Line/Symbol] * Depth.
- Click OK and the results are the Au concentration value multiplied by their depth value.
