A is sandstone.


The oldest rock shown is Q.
The oldest rock shown is K.
L is older than A.
The youngest rock shown is A.
The youngest rock shown is L.


I is older than K.
E is younger than F.
M is older than N.
N is a dike.
L is a sill.

The wavy line between H and G is a fault.
G was deposited immediately after H.
The rock represented by B and D formed at the same time.
C is a lava flow.
C is a sill.


C is a dike. [R is a terrace.
The stream has been rejuvenated.
S is a floodplain.
T is a natural levee.]
