Description / Table of Contents:
The various rock lithologies present on Macquarie Island are described in detail together with their mode of occurence and field relations. The four predominant rock types are pillow basalts, dolerite dykes, troctolites and gabbros, and ultramafics (mainly harzburgite). This sequence represents a section through the earth's oceanic crust. The dominant structural geological feature is faulting at any scale. Faulting also controls the evolution of the Macquarie Ridge complex, of which the uppermost part is the Island. It is concluded that the sequence of rock units present on Macquarie Island generated at the Australian-Antarctic spreading ridge.
