This major boundary is shown to be defined not by the traditional \"Friction Breccia\", but by a much earlier and more extensive mylonite zone. The mylonitisation was produced by a complex westward upthrust of the Kongsberg Series over the Telemark Series; both blocks had a common history thereafter. Spatial and chronological relationships between the upthrusting,, an extensive series of gabbroic intrusions and an increased heat flow, suggest association with major crust- mantle processes. The only major bend in the Kongsberg Series margin occurs in this area and in its location and development are explained.
