Part D
Geology of the Rhyolite Cliffs
One additional feature since the previous lab's sequence diagram is a lava flow, which may look similar to a sill since both may follow the layering of other rocks. However, lava flows typically have a "baked zone" on the bottom of the unit, but not on the top. This is different than with sills, which have "baked zones" all around their margins (both top and bottom).

Quiz Me! questions D46 through D50 refer to the Rhyolite Cliffs sequence diagram (Figure 6-10). If necessary, you can print a hard-copy of the diagram (see the link above). Also refer to the Key to Map Fill Patterns (click HERE for a printable PDF version).
