Figure 9. columnar basalt displaying large-scale sinu-
osity and small-scale undulation due to successive cooling
allowing joint propagation to greater depth. locations:
chile and Greenland.
Figure 10. Mostly small-scale planarity and small-scale
roughness down each column. suggested Q' classifica-
tion would be (90 -100)/9 × (1.5 -3)/1. The six sides of the
hexagons are equivalent to Jn = 4.
