| Abstract | Thermal water (ab. 29 e/,) is discharged near a greywacke basement-Tertiary sediment contact over a distance of 0.5 km by a few hot springs (Tmax = 67?C) and by seepage along the Te Maire Stream near Naike (70 km S of Auckland, NZ). The springs discharge a dilute alkaline, NaC1-type water which shows affinity to the chemistry of other thermal springs in the greater area occurring in a similar geological setting. The hot springs at Naike are fed by two NE-striking fracture zones which are connected by subsidiary fractures and joints. No significant, concealed outflow has been observed, and the shallow reservoir of the system appears to be restricted to the fracture zones. |
