Band colour = period; texture = dominant rock type. Lines between bands mark the contact type (wavy = unconformity inferred from a missing period). True scale makes height ∝ recorded thickness; hatched = thickness not recorded. Ages approximate, for ordering.

This unit (highlighted) within its province column; faded ends continue above and below. Line style marks the contact type.
