Abstract
The Martins Bay district, 12 miles north-east of Milford Sound, includes part of the southern end of the Alpine Fault. North-west of the fault thermally metamorphosed greywacke and argillite is correlated with the Waiuta Group and thought to be Precambrian in age. From Milford Sound north for 6 miles a wedge of marble and carbonaceous argillite (Kaipo Formation) with thick bands of pyritised granite lies between the fault and the Waiuta Group, and is thought to be the faulted north-eastern extension of the Ordovician rocks of southern Fiordland, Fiordland gneiss lies to the south-east of the fault. A coastal strip of Tertiary rocks without diagnostic fossils is correlated with rocks of the Paringa district. The Penguin Rock Breccia, thought to have been produced by volcanic eruptions, is the oldest. The Otitia Formation rests unconformably on the Waiuta Formation and on the Penguin Rock Breccia, consists largely of limestone, and is considered to be Oligocene. The Tititira Formation is faulted ag...
