Scientific paper

X-ray photoelectron spectroscopy was performed on a Luna-16 soil sample (number 1608-1) in order to study the reduction behavior of the constituents Fe, Ti and Si during heating in a hydrogen atmosphere. Results were compared with those for an earth rock - of gabbro-anorthositic composition - tested under the same conditions. It was found that after heating in hydrogen the iron oxide had practically vanished, the amount of reduced Ti exceeded the amount of oxidized Ti, and the amount of reduced Si had increased significantly. A comparison with the earth sample showed that lunar soil has a higher reduction potential, a fact possibly explained by the effects of cosmic rays and meteoritic bombardment on lunar soil.
