Pieters and coworkers have identified mare basalt units on the moon with a unique combination of spectral characteristics using near-IR spectra of individual locations within maria. The units, occurring in western Imbrium and near the crater Flamsteed and designated HDSA and hDSA in the notation of Pieters (1978), were interpreted as being relatively high in titanium, and exhibited the peculiar characteristic of having a weaker 2-micron pyroxene band than 1-micron pyroxene band. This latter characteristic was attributed to several possibilities, but most likely to us was the interpretation that these mare basalts contain abundant olivine. Olivine is present in varying amounts in basalts and has no 2-micron band, but exhibits a strong 1-micron band. Invoking abundant olivine seems the simplest explanation for the spectral characteristics of these basalts.
