Fossil track analyses of impregnated core sections from the Apollo 15 and 16 deep drill cores were used to study two types of distinct layers of about 1 mm and about several mm thick in the lunar regolith. The data supports a mixing model hypothesis for the origin of the sampled soil column dominated by large, fresh feldspar fragments. The boundary track method and the track gradient method were used to study the compaction ages of lunar breccias.
