Subsurface Hydrothermal Alteration in the Kamojang Geothermal Field, West Java, Indonesia
The presently vapor-dominated Kamojang geothermal field is located in West Java (Indonesia). The field lies in high terrain, 1500 m above sea level, and is hosted by volcanic rocks. Samples from seven wells were kindly made available for this study, namely from KMJ-7, KMJ-10, KMJ-11, KMJ12, KMJ-53, KMJ-59, and CHR-1 drilled to depths ranging from 536 – 1804 m. The reservoir is hosted by interbe...
متن کاملAdaptive Neuro-Fuzzy Inference System application for hydrothermal alteration mapping using ASTER data
The main problem associated with the traditional approach to image classification for the mapping of hydrothermal alteration is that materials not associated with hydrothermal alteration may be erroneously classified as hydrothermally altered due to the similar spectral properties of altered and unaltered minerals. The major objective of this paper is to investigate the potential of a neuro-fuz...
متن کاملGeologic Framework of Jurassic Reservoir Rocks in the Dixie Valley Geothermal Field, Nevada: Implications from Hydrothermal Alteration and Stratigraphy
The main reservoir in the Dixie Valley geothermal field of Nevada is hosted in fractured Jurassic rocks within the hanging wall of the Stillwater fault. Within the Jurassic sequence, at least four major stages of alteration related to the fault system can be identified. The paragenetic sequence from oldest to youngest consists of Stage I) biotite-potassium feldspar veins, and epidote-chlorite-c...
متن کاملa new approach for hydrothermal alteration mapping by selecting and interpreting principal components in landsat etm+ images
introduction in remote sensing studies, especially those in which multi-spectral image data are used, (i.e., landsat-7 enhanced thematic mapper), various statistical methods are often applied for image enhancement and feature extraction (reddy, 2008). principal component analysis is a multivariate statistical technique which is frequently used in multidimensional data analysis. this method atte...
متن کاملTemperature Mapping Using Ultrasound Digital Images
Introduction: The success of hyperthermia depends on the accuracy of the temperature monitoring in the tumor and the surrounding normal tissue. In this study, the temperature changes were determined by computing the speckle displacement in the ultrasound digital images. Speckle tracking algorithm was used to compute the displacement. Materials and Methods: The experiment was perf...
