FIGURE 66.-Aluminum-silicon ratios measured along one track of Apollo 15 . Note the excellent correlation between the intensity and different lunar regions. The maria have low ratios, the Highlands have high values. These data support the idea that the lunar Highlands consist mostly of anorthosite, an aluminum silicate rock. Similar data will be obtained with identical equipment on Apollo 16. Data provided by Dr. I. Adler, the Principal Investigator of this experiment. NASA PHOTO S-72-16319.
