Appraisal of the Tokaanu-Waihi geothermal field and its relationship with Tongariro geothermal field, New Zealand

摘要

Tokannu-Waihi geothermal field is situated near the southern end of the Taupo Volcanic Zone, New Zeland. Neutral chloride thermal waters discharge at Tokaanu and Waihi in the North of the field on flat land between the andesite volcanoes Tihia and Kakaramea and the shore Of Lake Taupo, while steam-heated thermal features occur at Hipaua on the northern flanks of Kakaramea. Electrical resistivity surveys have been made over the field using several different Measurement techniques.
