Notes
The vertical electrical sounding surveys encountered few difficulties and were able to resolve basement resistivities in all locations. The resistivity sections derived indicated a 3000- 20,000 ohm.m surface layer underlain by a 500- 900 ohm-m cold freshwatersaturated layer and a basement layer of less than 100 ohm.m (Kauahikaua and Mattice, 1981). The depth of penetration of these soundings was estimated to be about 800 m to 900 m b.s.1. and thus the basement resistivities probably correspond to basalts containing cold fresh to saline water.
