✦ Synopsis

The hot spring waters discharging in the Tulehu peninsula of Ambon island\ Indonesia\ vary in composition from NaÐCl!type to NaÐClÐHCO 2 !type[ Most chemical characteristics of the NaÐCl!type waters are typical of liquids circulating in high!enthalpy geothermal reservoirs[ Mixing trends in the plots of alkali vs Cl suggest the existence of a parent geothermal liquid with Cl content of 03\999 mg:kg[ The NaÐK geothermometer indicates deep temperatures of 129Ð134>C[ The parent liquid cools through conduction and:or mixing with cold\ low!salinity groundwaters[ SodiumÐClÐHCO 2 !type waters originate from dilution of the parent liquid accompanied by waterÐrock interaction under high P CO 1 conditions[ Þ 0888 CNR[ Published by Elsevier Science Ltd[ All rights reserved[
