Missing Strata Report

This command reports strata from the selected drillholes that are missing in the strata sequence. The strata sequence is determined by reading the strata from all the selected drillholes. When a strata is missing between other strata, this is reported as PINCH OUT. For example with strata A,B,C and a drillhole with A,C, then strata B will be reported as pinch out. If a strata is missing before the first strata in the drillhole, then this strata is reported as ABOVE. For example a drillhole with B,C would report strata A as above. Likewise a strata missing after the last strata in the drillhole is reported as BELOW. For example a drillhole with A,B would report strata C as below. In the report, the estimated bottom strata elevation and thickness for the missing strata is reported based on pinch out and conformance.
