This routine inserts an interval into the drillholes at either the
very top or the very bottom of the selected holes. It is necessary
to do this for certain types of geological modeling that have the
top or bottom seam disappearing, and not all intervals in the hole
have a bed name, such as in this lignite modeling. It “borrows”
thickness from either the top or bottom interval, as in this
example shown below in the ROCK strata. Some prefer to enter in a
0.1 interval and just call it TOP.
It went from 99 to 98 thick, with the addition of 1 foot of topsoil. This will aid in the modeling of the seam C1 in holes where it does not exist, due to pinch or erosion. This routine should not be used in holes that are drilled in a valley, and the C1 seam is above the collar; it will be modeled with conformance.
Add strata to top or
bottom of drillhole [<Top>/Bottom]? Top
(in this example)
Enter strata name: Topsoil
Enter bed name: Top
Status for strata [<Key>/Non-key]? N
Enter strata thickness: 1.0
