A serpentinite occurrence with metasomatised gabbro and rodingites.

Company employees call this active mine site, the Wairere Serp (short for serpentinite) Quarry.

The quarry is owned and operated by Rorisons RMD Limited, producing agricultural lime. The quarry produces 120 000 tonnes of lime per year. Any specimens, if they exist at all, are likely to have been crushed into a fine powder, then spread across farmland in the district. The quarry is 10 kilometres south of Piopio, in a pervasively bucolic rural area. Rorisons also owns the new Riverside Quarry established in 2015, one kilometre north of the Wairere Serp Quarry, and part owns the small Aria Quarry (historically called Ratima's), 2 kilometres to the west south-west. An old council road metal quarry is one kilometre to the north-west of the Wairere Serp Quarry.

Geology sources date from the early 1970's, when the quarry provided access to the Wairere Serpentinite, a 650 metre long by 50 metre wide serpentinite lense, along the north north-east trending Waipa Fault. The quarry had been operational since the late 1940's.

The quarry contains numerous small highly altered hard grey dense eucritic to hornblende gabbros, with rodingite margins. The alteration is caused by Ca and Al rich solutions derived by the actions of alkaline CO2 poor solutions, percolating through the host peridotite, and via serpentinization from rich Mg, and enhanced Ca and Al levels.

Four types of serpentinite occur being massive blue-black, green-black, mottled olive-green, and mottled blue-black, although recent pictures of the quarry only show near surface white soft crumbly material. Most attention has been focused on species (some rare for New Zealand) at the serpentinite-rodingite contact.

The gabbro contains albitised plagioclase, converted in part to prehnite and clinozoisite; clinopyroxene and hornblende altered to chlorite, with skeletal leucoxene common. Intense metasomatism results in garnetisation of the prehnite, and production of secondary clinopyroxene and amphibole at the margins of the gabbro with the rodingite. The original harzburgite has been highly altered to serpentinite, and at the contact with the gabbro to blue-green chlorite. Hornblende gabbros contain abundant sphene, and late stage serpentinite veins, with an absence of pectolite and prehnite.

The serpentinite contains relic olivine, clinopyroxene, orthopyroxene, anhedral chrome spinel, minor fibrous brucite around the edges of some bastites as small veins, and associated with pyrite and magnetite in secondary serpentinite veins. Aragonite and calcite is abundant, the aragonite forming pseudohexagonal crystals in stock work veins, and coating shear planes.

Garnet appears to be massive only, as colourless hydrogrossular, or more common andradite in rodingite. Chromian chlorite occurs as large pods in rodingite, some filling fractires in diopside. Some authors identified xonotlite, while others found its sodium cousin pectolite only. Either one was found at the contact, as a 1 mm to 1 cm crust separating the serpentinite with the rodingite. The material is mainly white, occasionally pink or pale green, and breaks into splinters typical of the species, with a pearly lustre. Pennine occurs in dark sheared serpentinite in veins and cavities at the contact with rodingite. Pennine, xonotlite and pectolite are rare in New Zealand. Orange-pink chromium chlorite is found in prehnite veins radiating from the serpentinite-rodingite contact. Material approaching chrysotile is said to be common.

Of interest is the very rare species rosenhahnite (nine other localities worldwide on Mindat at the time of writing). It is associated with pectolite as rounded to angular fragments in a brecciated zone, at the base of highly weathered pectolite-prehnite crust at the serpentine-rodingite contact. It appears specialist equipment is needed to identify, and is not specimen grade.
