| dc.description.abstract | This research discusses the application of gravity method in delineating structures at Utah, United States of America, there are two types of geothermal system, Roosevelt Hot Springs-a conventional geothermal system and FORGE Utah Site-an unconventional geothermal system. Structures are analysed by producing maps of Horizontal Gradient Magnitude (HGM) and Second Vertical Derivative (SVD) from the gravity data. Interpretation is also supported by other data’s such as geological information, well information, and interpretation from TEM and seismic. Three structures were able to be identified in this research which are also supported by other data, they are Opal Mound Fault, Negro Mag Fault, and Mineral Mountains West Fault. Opal Mound Fault is interpreted to act as boundary of the Roosevelt Hot Springs geothermal system and holding back the convective flow to the west, but still allowing the conduction to occur and create a high thermal gradient for the FORGE Utah Site, making it potential to develop an Enhanced Geothermal System. The Complete Bouguer Anomaly map shows high density on the eastern area which is interpreted as the distribution of granitoid rocks and HGM map shows maximum anomaly at the central area which is interpreted as the sedimentary basin. | en_US |
