Create a Density-Depth Table

Use this dialog (DDT > Create DDT menu) to define the vertical density-depth table (DDT) for your model. The new distribution will be created and displayed in the Properties panel. Here you may populate the table by entering offset-density pairs in the table.

Create Density-Depth Table dialog options

New DDT name

Provide a descriptive name for the table.

Reference surface type

Specify whether the reference surface is defined by an elevation grid in the workspace, or an existing layer in the model.
 

Reference surface grid

Browse to find the reference elevation grid.

Reference layer

Select the reference surface from a list of layers in the model.

Density

The density at offset = 0

Application Notes

The table hangs on the "reference" grid and can apply to an unlimited number of blocks in the model. You must specify the number of (depth, density) pairs prior to entering the values. Offset entries must be increasingly negative.
