If the intruded rock is rich in carbonate the result is a skarn.

In this region, as in many others, the intruded rock is more resistant than the surrounding country rock and gives rise to prominent topographic features (Fig. 7.26).

As the mantle plume intruded rocks of the Canadian Shield, it created an upwelling zone of molten rock known as the Mackenzie hotspot.

The Riwaka Complex intruded rocks on the west of Abel Tasman National Park, south to the Baton River Area.
