Relative Concentration Of Various Elements On The Lunar Surface
Relative Concentration (in weight ppm) of Various Elements on Lunar Highlands, Lunar Lowlands, and Earth

The layer of debris which blankets most of the moon is commonly refered to as regolith. Billions of years of bombardment from space has created a highly comminuted (this means it has been broken into ever smaller grains and particles) surface through a process sometimes referered to as "impact gardening" or "space weathering." It is estimated that the regolith varies in thickness from 3 to 5 meters over the younger "maria" to approximatly 10 to 20 meters thick in the older "highlands." Below the impact regolith is a layer of "mega-regolith" consisting of highly fractered bedrock that is tens of kilometers thick.

The portion of the regolith of a size less than 1cm is generally referred to as Lunar Soil, and the dusty, abrasive portion is referred to as Lunar Dust or "Fines."

Lunar regolith is the focus of many proposed methods of oxygen production and in-situ resource utilization including:
