Applied orbital spectroscopy for geothermal alteration cap mapping, microseepage identification, and pipeline corridor terrain stability. We demonstrate how narrow SWIR ammonium illite signatures and thermal inertia anomalies pinpoint blind hydrothermal reservoirs without destructive surface disruption.
Key findings
- Ammonium illite absorption at 2.120 µm reliably marks high-temperature boiling zones and geothermal upflow channels.
- Surface mineral alteration induced by reducing hydrocarbon microseepage exhibits detectable bleaching of hematite and anomalous clay recrystallisation.
- Diurnal thermal inertia modeling maps subterranean void formations and moisture emergence along 200+ km pipeline corridors.
