1. Sample 72275 is a friable fragmental Breccia from the edge of the Serenitatis basin

2. Scoria may form as part of a lava flow, typically near its surface, or as fragmental ejecta (lapilli, blocks and bombs), for instance in Strombolian eruptions that form steep-sided scoria cones.

3. Colluvium fragmental material accumulating on mountain slopes or at the foot of slopes owing to displacement from higher areas by gravity (talus, creep, and slides) or the movement of thawing, water-saturated products of weathering in areas of permafrost
