Murihiku Supergroup (Triassic—Jurassic) of Southland and South Otago

Abstract

The name “Murihiku Supergroup” is proposed for those rocks, in general of older Mesozoic age, which overlie the Permian Bryneira, Productus Creek, Arthurton, and Kuriwao Groups in the Southland Syncline and underlie the erosion surface on which Cretaceous and Tertiary beds were deposited with major unconformity. North Etal and Taringatura Groups are introduced; North Range and Wairuna Peak Groups are given formal status. All are included in the Murihiku Supergroup.
