68501 (102) - Highland Regolith Soil
 >View Microscope
Fact sheet
Description: 

Sample 68501 is mature lunar soil known as a regolith, which was collected at Station Eight during the Apollo 16 mission. Regolith is produced from the fine-grained debris formed in both large and small impacts. Agglutinates (clusters of dust welded together to form larger particles) in the soil form by melting due to continual bombardment of the Moon’s surface by micrometeoroids.

This sample was sieved to remove the very fine dust, allowing examination of the range of large fragments. It mainly consists of fragments of highlands rocks, anorthosite, norite and microbreccias, impact-produced glass and agglutinates. The soil shows that the Lunar Highlands are very rich in plagioclase feldspar but contains relatively few fragments of mare basalts.
