NASA Lunar Petrographic Educational Thin Section SetC Meyer - 2003 Lunar RegolithFigure 54 Footprint in lunar soil. Few rocks are sitting out on top of mature Regolith . NASA photo lunar surface is covered by a layer ofunconsolidated debris called the lunar Regolith (fig. 53).The thickness of the Regolith varies from about 5 m onmare surfaces to about 10 m on highland surfaces. Thebulk of the Regolith is a fine gray soil with a density ofabout g/cm3, but the Regolith also includes brecciaand rock fragments from the local bedrock (reviewsby Heiken et al.)
bulk of the regolith is a fine gray soil with a density of about 1.5 g/cm3, but the regolith also includes breccia and rock fragments from the local bedrock (reviews by Heiken et al. 1974 and Papike et al. 1982). About half the weight of a lunar soil is less than 60 to 80 microns in size. The grain size distribution is given in figure 55.
