A supracrustal sequence of carbonates and clastic metasediments, interdigitating with metavolcanics occur in this area, intruded by a series of dykes. The majority of minor intrusions are mafic in composition; a minor number of felsic samples have been identified.

Four distinct geochemical suites have been recognized: a Low Zirconium Suite of tholeiitic basalts, an Intermediate Zirconium Suite of tholeiitic basalts, andesites, dacites and rhyodacites, a Calc-Alkaline Suite of basalts, andesites and rhyolites, and a Highly Fractionated Tholeiite Suite consisting of a single, unevolved tholeiitic basalt. The geochemical suites were modelled from three distinct sources; two spinel lherzolites and a garnet lherzolite, by partial melting and fractional crystallization.
