From: ASTER, ALI and Hyperion sensors data for lithological mapping and ore minerals exploration
Geological applications | Lithological and structural mapping | Porphyry copper and epithermal gold | Chromite and magnetite | Mineral components of soils | Massive sulfide |
---|---|---|---|---|---|
ASTER | Identification the variety of igneous felsic, mafic-ultramafic rocks, metamorphic rocks, sedimentary rocks, and ophiolite components. Faults, fractures, anticlinal or synclinal faults, and lithological boundaries. | Identification and discrimination of gossan, argillic, advanced argillic, phyllic, potassic, propylitic and silicic zones. | Detection of serpentinized harzburgite.Identification of magnetite quartzite, sodid-calcic zone, potassic and silicic-phyllic patterns. | Identification the variety of iron oxide/hydroxid-es minerals, clay minerals chlorite and epidote mineral groups, carbonate minerals, and silicate minerals. | Detection of gossan, propylitic, and silicic zones. |
ALI | Detection the variety of igneous, metamorphic, sedimentary, and ophiolite rock complex. Faults, fractures and lithological boundaries at regional scale. | Identification of hydrothermally altered rocks at regional scale. | Identification of serpentinized harzburgite. Iron oxide/hydrox-ides minerals. | Detection and discrimination the variety of iron oxide/hydroxid-es minerals. Identification of clay minerals at regional scale. | Detection of gossan. |
Hyperion | Chemical composition of different types of rocks and mineral abundance in the rocks at district scale. Detection of lithological boundaries, faults, fractures, and joints at district scale. | Detection the abundance of specific minerals in hydrothermal alteration zones at local and district scales. | Detection of serpentinized harzburgite. Identification of magnetite quartzite, sodid-calcic zone, potassic and silicic-phyllic patterns at district scale. | Detection the abundance of iron oxide/hydroxid-es minerals, clay minerals chlorite and epidote mineral groups, carbonate minerals in the soil at local and district scales. | Detection of gossan and propylitic zones at local and district scales. |
