The Tauhara geothermal system 1)underlies Taupo on the of the extinct Tauhara dacite volcano. The resistivity boundary shows that the field is connected with the field 6 away. 4 deep wells, showing that the geology and geochemistry are similar to Wairakei although well encountered somewhat higher temperature and gas content. The field has been explored with Up to the natural activity of boiling chloride springs beside the river, and dilute chloride springs in the area, with steam-heated waters and steaming ground in the N.E. Sarbutt (1964) the chemistry of these waters and showed the presence of a dilute sulphate-chloride mter in shallow wells adjoining steaming ground areas. contents reflect saturation with respect to derived from the pumice.

Flows of cold in the surface deep system steam to hot steam-heated waters which became progressively diluted deep steam may be by a structural high in the |
