Water Geochemical Analysis Within Penantian Geothermal Area In Pasema Air Keruh Kabupaten Empat Lawang

Abstract

Geochem ical analyzes have been conducted on several samples of water geothermal manifestations are located in the Penan tian village, Pasema Air Keruh subdistrict, Empat Lawang district, South Sumatra. Water Geochemical analysis use geothermometer, ion balance and geoindicator methods to determine the temperature and the characteristics of the reservoir. From the data processing obtained that the composition of Penantian geothermal wa ter is the sulfate and carbonate types. This indicates that the hot water corning from the volcanic and heat sources are not too deep below the surface. While the estimated reservoir temperatures above 300°
