Mixing of Major Soil Components in the Apollo 16 Drill Core
Physics and Astronomy
Two major processes are thought to act on lunar soils, maturation and mixing. Petrologic data, inert gas data, and magnetic data show convincingly that mixing of a least three major soil types is a significant contribution to the gross stratigraphy of this core. The evidence, however, does not exclude in situ maturation.
