Mô tả: A few small areas on the moon with extremely low albedo are shown also to have similar spectral reflectivity and radar backscatter characteristics. These lunar ‘black spots’ include the dark mantling material of the Apollo 17 landing site as well as areas of the Sulpicious Gallus formation. Excluded from the black spot group are the dark haloed craters of Alphonsus and the normal dark mare areas such as northern Mare Tranquillitatis. Earth‐based radar and optical measurements indicate that these lunar black spots have rock‐free surfaces with a very low proportion of crystalline material to amorphous material. The glassy soil is rich in iron and titanium, at least to the concentrations found at the Apollo 11 site. Crystalline pyroxene is present also. The data for the black spots are consistent with a mantling material of ash or cinder.
