Bidirectional reflectances for the blue, green, and red channels were determined for 31 block and soil exposures imaged by the two Viking Lander Cameras on Mars and were calibrated to within 10 percent uncertainties. The observed variations in bidirectional reflectance in the visible and relative brightness in the IR could be best explained by varying degrees of oxidation and ferric iron crystallinity, while most block surfaces had reflectances consistent with thin to optically thick covers of palagonitic material. These results are consistent with the conclusion that blocks seen at both sites are mafic rocks coated to varying thicknesses with amorphous oxidized material. The differences observed in reflectance properties for common block surfaces and common soils imply that local weathering of blocks has not contributed significantly to the soil exposed at the landing sites.
