... as a geochronologic target to elucidate the thermal histories of youthful geothermal systems ( Hulen et al., 1997 ). Drill cores recently recovered from the Tauhara sector of the joint Wairakei and Tauhara geothermal fields (Wairakei-Tauhara) of the TVZ (Fig. DR1 in the GSA Data Repository 1 ) intersected...

... be applied to detect areas of subsidence within geothermal fields. Although subsidence is not observed at Ngatamariki, areas of anomalously high subsidence (up to 2–3 m) often form within fields, which can cause damage to the built environment. At the Tauhara geothermal field in New Zealand, this was shown...
