Resistivity Resurvey of Southern Tauhara Geothermal Field

Abstract

Over a hundred new resistivity measurements were made throughout the southern and eastern Tauhara Geothermal Field in 1988-89 using the Schlumberger electrode with spacings of m. When collated with the data measured during 1982,the total set gives good coverage along southern boundary of the Tauhara Field, but coverage is still sparse in several important regions including the of Tauhara, the foreshore of Lake Taupo and the northern parts of the field. The size of the Tauhara Geothermal Field defined by the area totally within the new resistivity boundary is about 35 much bigger than indicated by earlier boundaries. The field extends further south and east than earlier measurements had indicated.
