Tertiary basalt with some zeolites. Tangihua Volcanics. Active quarry worked by the local council. Located 5 kilometres west of Wellsford. Not really near the locality of Te Hana.
Analcime as distorted dodecahedrons, associated with other zeolites. Calcite by itself and with zeolites, most commonly dog tooth form, and rarely pseudo cubes. Often found perched on natrolite needles. Chlorite by itself and sometimes with analcime, as minute rosettes. Natrolite as well formed needles, sometimes with calcite suspended on them.
