    The Adirondack Highlands host several anorthosite intrusions, the largest of which is the heart-shaped Marcy massif. The late- to post-orogenic settings of AMCG complexes have lead authors to suggest a delamination origin for Proterozoic anorthosite complexes (McLelland et al., ; Valentino et al., ). AMCG rocks in the Adirondack region.

From the small pebbles that get into our shoes to the glacial erratics and mountains that make the Adirondacks what they are, all these rocks originated in the thin layer that covers the molten and semimolten mass that forms the .

A major lateral velocity change in the upper and mid crust occurs between the Appalachians and the Adirondacks. This boundary, projecting to the surface beneath the Champlain Valley, dips to the east beneath the Green Mountains and extends to a depth of ∼25 km below the eastern edge of the Connecticut Valley Synclinorium in Vermont.

During and after active tectonism (extension, thrusting or shearing), fluids may be abundant in the deep crust and may be associated with such diverse phenomena as granulite-facies metamorphism, shear zone alkaline granites, carbonatite-lamprophyre-syenite complexes, and various kinds of metasomatism, including .
