The research site is administratively located in Bandung Regency, West Java Province. This area had a unique morphology forming a horseshoe composed of Quaternary volcanic rocks which is a geothermal field. This study aimed to discover the relationship between geomorphic index characteristics to the geothermal manifestation appearance in the research site through 3D modelling using micromine software. The results of the geological lineament analysis were interpreted as geological structures trending west-east (W-E), northwest-southeast (NW-SE) and northeast-southwest (NESW). Geomorphic index characteristics showing active tectonic class (Smf value: 1,34 – 1,99) and medium (Smf value: 2,06 – 2,41), medium lineament density (Ld value: 1,013 – 1,229 km/km²), and height (Ld value: 1,229 – 1,900 km/km²). 3D modeling using micromine software clearly showed the continuity of geological structures on the surface to the subsurface. The accumulation facilitated geothermal fluids from beneath the surface to move and emerge on the surface as geothermal manifestations. The spread of geothermal manifestations can be divided into three groups, which are: TKR-1 group (Subwatershed CTR-2, CTR-4, CLK-3, and CLK-4). TKR-2 group (subwatershed CTR-3, CLK1, and CLK-2), TKR-3 group (sub- watershed CTR-1 and CLK-5).
