Tr, reservoir temperature; nd, not detected. *1Temperature was calculated using the quartz geothermometer with adiabatic cooling (Truesdell, 1976), *2Temperatures
estimated from the Na-K-Ca geothermometer (Fournier and Truesdell, 1973). Gas composition was calculated using the chemical composition of steam discharged
from geothermal well and Tr.
