Geologically the range is composed of Ordovician ocean floor rock which includes an ophiolite unconformably overly the ophiolite and granite intruded the area during the Devonian.

The Dalradian metasedimentary rocks are overlain by an obducted ophiolite that is continuous for at least several kilometers on either side of the Highland Boundary Fault.
43.
In terms of ophiolite emplacement, there was a problem of how to uplift dense oceanic lithosphere through 5 6 km of water and onto continents.
44.
Other sources of magnetite iron ore include metamorphic accumulations of massive magnetite ore such as at Savage River, Tasmania, formed by shearing of ophiolite ultramafics.
45.
Many surface exposures of ultramafic rocks occur in ophiolite complexes where deep mantle-derived rocks have been obducted onto continental crust along and above subduction zones.
46.
This last fact was first pushed by Akiho Miyashiro in 1973 who challenged the common conception of Troodos Ophiolite and proposed an island arc origin for it.
47.
Pinatubo is flanked on the west by the Zambales Ophiolite Complex, which is an easterly-dipping section of Eocene oceanic crust uplifted during the late Oligocene.
48.
The "'Lizard Complex "', Cornwall is generally accepted to represent a preserved example of an exposed ophiolite complex in the United Kingdom.
49.
The rocks found in The Lizard area are analogous to those found in such famous areas as the Troodos Mountains, Cyprus and the Semail Ophiolite, Oman.
50.
An ophiolite and Peridotite complex, the Lewis Hills is the southernmost of four such complexes located within the Humber Arm Allochthon, a world-renowned geological area.
