Analyses of waters from many New Zealand hydrothermal areas (both volcanic and non-volcanic) are presented for discussion. The natural hot-water compositions are compared with those resulting from the experimental interaction of water at 150-350°C with volcanic rocks and a greywacke from the central part of the North Island of New Zealand. Appreciable quantities of the minor components Cl, B, F, As and NH 3 were liberated into solution from the rocks along with silica and alkalis. The ease of solution of the former group of elements, the kinetics of solution, and the slight degree of rock alteration, showed that they existed to a large extent on surfaces in the rocks (particularly for crystalline rocks) rather than in silicate structures. It appears that volcanic thermal water compositions could be approached in nature by the reaction of high-temperature water with rock, without requiring a contribution from a "magmatic" fluid rich in the typical hydrothermal phase elements. It would be difficult to define the so-called "magmatic" solutions supposedly involved in the genesis of volcanic hydrothermal systems, as key elements such as lithium, caesium, chloride and boron would at equilibrium be concentrated into a hot-water phase interacting with either crystalline silicates or a rock melt. Preliminary experimental work at 500-600°C adds support to this suggestion. The composition of solutions obtained from the interaction of greywacke and water was of similar type to that of warm springs occurring in this rock.
