Alpine-type Serpentinites from the Auckland province—I. The Wairere Serpentinite

Journal of the Royal Society of New Zealand, 1973
Abstract The Wairere Serpentinite, exposed over 650 m along the trace of the Waipa Fault near Piopio, lies close to the boundary of the marginal and shelf facies of the New Zealand Geosyncline and hence close to Hatherton and Sibson's magnetic junction anomaly.

Alpine-type serpentinites from the Auckland Province—II. North Auckland serpentinites

Journal of the Royal Society of New Zealand, 1973
Abstract Eighty discrete lopolithic-shaped bodies of serpentinite ranging from 350 m3 to 24 000 m8 in size are found in North Auckland, south of Whangarei and east of Hatherton and Sibson's (1970) junction anomaly, within the Onerahi Chaos-breccia Formation. The bodies are confined to valley floors or low on the flanks of hills.

Serpentinite: What, Why, Where?

Elements, 2013
Rock-forming serpentine minerals form flat, cylindrical, and corrugated crystal microstructures, which reflect energetically efficient layering of alternate tetrahedral and octahedral sheets. Serpentinization of peridotite involves internal buffering of the pore fluid, reduction of oxygen fugacity, and partial oxidation of Fe 2+ to Fe 3+ .

The Sierra Nevada serpentinites: the serpentinites most used in Spanish heritage buildings

Geological Society, London, Special Publications, 2014
Abstract Serpentinites from Sierra Nevada (Granada, south of Spain) have traditionally been used as ornamental elements in historical buildings, both indoors and outdoors. The cathedral, the Palace of Charles V, the Royal Chancellery in Granada and some others are good examples of their use.
