Abstract Steatite occurrence and deposit around Andale village have been identified and demarcated. Steatite (or Soapstone) is a compact, often impure variety of talc. Steatite is widely being used as industrial natural resource material due to good workability and heat retention characteristics. It is used in cookware, cook tops, oven floors, masonry heaters, fireplace liners, carvings, beads, mold and electronic insulator etc. Precambrian rocks of Karnataka hosts many economic valuable mineral deposits in that steatite is one among them. Fresh samples of steatite and Peninsular gneiss were randomly collected in the field through GTC (ground truth check). Rock samples were studied under transmitted light microscope, SEM-EDX and Spectro-Radiometer. Spectral signatures were studied by Spectro-Radiometer (Spectral Evolution SR-3500) instrument, DARWinSP.V.1.3.0 and ArcGIS software. Petrography helped to know the other minerals which are associated with steatite, SEM-EDX studies helped to know the high Mg elemental percentage present in the given steatite sample. The spectral signatures of the collected samples were derived in laboratory environment to achieve better accuracy. Spectral signature curves of steatite and other samples were derived based on their physico-chemical and optical properties. The final results highlight the spectral characters of steatite for better mapping in similar terrains around Andale village of Hassan district of Karnataka State.
