Also Sugarloaf Islands. Cox, S.H. (1882)also refers to the islands as the Sugar Loaves, but it would appear that this term is incorrect.
The GPS coordinates are for the five Sugar Loaf Islands in general.
The islands are the type locality for taranakite, the first new mineral species discovered in New Zealand. Taranakite is a hydrated iron aluminium phosphate mineral, formed from the interaction of clays and alumino rocks with enriched phosphate from bird guano on the islands.
The exact position of the type locality for taranakite is not detailed by Hector & Skey (1865) or Cox (1882).
Taranakite was first identified by James Hector (government geologist) and William Skey in 1866, from material collected by H. Richmond, as thin yellowish-white amorphous seams in fissures in hornblende andesite.
Within this is dark yellow-brown seams initially identified as wavellite, however a chemical study of the material in 1946 (Bannister et. al., 1946), identified the material as vashegyite. Wavellite is now doubtful for the location.
Taranakite is also found at Chrystalls Beach (Cooks Head Rock), Clutha District, Otago Region, New Zealand.
