Taranakite
Taranakite is a hydrated alkali iron-aluminium phosphate mineral with chemical formula . It forms from the reaction of clay minerals or aluminous rocks with solutions enriched in phosphate derived from bat or bird guano or, less commonly, from bones or other organic matter. Taranakite is most commonly found in humid, bat inhabited caves near the boundary of guano layers with the cave surface. It is also found in perennially wet coastal locations that have been occupied by bird colonies. The type location, and its namesake, the Sugar Loaf Islands off Taranaki, New Zealand, is an example of a coastal occurrence. Taranakite forms small white, pale yellow, or gray crystals, which are typically found in pulverulent nodular aggregates, or crusts. Taranakite crystallizes in the hexagonal system, and is noted as having the longest crystallographic axis of any known mineral: the ''c''-axis of the taranakite unit cell is 9.505 nanometers long.

Sugar Loaf Islands
The Sugar Loaf Islands (often Sugarloaf; mi, Ngā Motu, ) are a collection of five small uninhabited islands and several sea stacks near Port Taranaki, New Zealand. The largest, Moturoa Island, covers approximately . Motumahanga is the island furthest from shore, at approximately . Ngā Motu was one of the first areas inhabited by descendants of Te Whiti o Rongomai, and the islands and reefs were all named by Ngāti Te Whiti. The island group was given its English name in 1770 by James Cook because the reminded him of the way sugar was stored in heaps in Europe. The Sugar Loaf Islands Marine Protected Area (SLIMPA) was established in 1991 to protect the area from oil exploration. This strengthened the protection that had been in place since the formation of a marine park in 1986. In 2013 New Plymouth district councillors unanimously agreed to gift the protected area back to the government for Treaty of Waitangi claims and settlements, treaty settlement negotiations with Taranak ...
