Infrared emissivity comparison spectra of nine areas on the lunar surface, each 40 km in diameter, indicate that the majority of the lunar surface, including the five Apollo sites, has a constant Si‐O ratio so far as present infrared techniques are able to detect. However, an anomaly in the 8.2‐9/μ region of the emissivity spectrum of the crater Plato is interpreted as evidence of a significantly different Si‐O ratio in the mineral assemblage exposed on that surface.
