Abstract :
White micas are commonly formed in hydrothermal mineralisation systems. Their compositional variations reflect physical and chemical conditions, and therefore are very useful for reconstructing extinct hydrothermal systems and guiding mineral exploration. Airborne hyperspectral sensing technology and field infrared spectroscopy are operational tools for identifying and mapping the compositional variations of white micas within a hydrothermal system
