| Abstract | The Wapsalit geothermal manifestation is located in Buru Island Indonesia. Geological stratigraphy of the area is even dominated by Paleozoic metamorphic rock. This study is focused on alteration study compared to the type of fluid geochemistry of manifestations. The manifestations consist of hot springs, hot ground, steaming ground and altered rocks. The manifestations are distributed along Waekady River and controlled by Waekedang oblique fault. The temperature of manifestations reaches 94°C. Base on mineral analysis, altered minerals are found such as illite and alunite. These minerals are hardly interpreted as result of hydrothermal alteration since the country rocks are metamorphic. |
