Abstract

Walat hills in the area of Sukabumi, has a pattern of east-west trending ridge. Hills line orientation is controlled by the structure of fold with is followed by formation of reverse fault. Both of geological structures is formed on the same tectonic period, on Plio-Plistocene. Position of the axis of the fold and reverse fault parallel relative to each other, based on the tectonic formation occurs in the same period, it can be classified as a pattern of thrust folds structure. Of some reverse faults that developed in Walat Area, the reverse fault whose position to northward is major reverse fault, so that by referring to the model structure of Boyer and Elliote (1982), it can be classified as a leading thrust system. This structural pattern is controling topographical differences of the hills with plain morphology in northern.

Abstract

This study aims to delineate the breadth and depth of the geothermal reservoir and the resulting temperature. The method used is a compilation of lithology, alteration and the temperature profile that is supported by literature references and well data. Delinasi prospect area and deep reservoir of data viewed by lithology, alteration and the temperature profile. Regional prospects in the region of 2000C or more temperatures are also characterized by the presence of epidote minerals and are on lava and pyroclastic stratigraphy perselingan. The results obtained two different reservoir sites, the first located at depths of 800-1300 m above sea level and an area reached 1.37 x 107 m2., While the second is located at a depth (900 m - bottom) and an area of more than 3, 38 x 106 m2. Based on the temperature profile, the type of prospect geothermal reservoir in this area is the type of dominance of steam. .
