POSC Specifications: Epicentre Version 3.0 Relational Implementation

GEOLOGIC_FEATURE_ASSOCIATION (GEOLOGIC_FEATURE_ASSOCIATION)

(DDL)

Describes the consequence of a relationship between two geologic features, primary and secondary. The relationship is asymmetric if the consequence applies only to the primary feature. If the consequence could apply equally well to either the primary or the secondary feature, the relationship is symmetrical and either feature may be arbitrarily assigned the consequence. Examples include; "a horizon is the top of a sand layer" (asymmetrical), or "a sand layer is interbedded with a shale layer" (symmetrical).
