Describe the geological features shown in Figure 4 and sketch and annotate it to show these features.

Here are the geological features from the image:

a) Draw and annotate a sketch of figure 4 in the space below to show the geological features present.
(Since I cannot draw, I will describe the sketch and its annotations.)
A sketch of Figure 4 should show two distinct rock units. The lower unit should depict multiple parallel layers that are tilted at an angle. The upper unit should be drawn as a massive, unsorted rock body with clasts, resting horizontally on top of the tilted lower unit. The boundary between the two units should be irregular.

Annotations for the sketch:

• Upper Unit: Dolomitic conglomerate
• Lower Unit: Tilted sedimentary strata
• Boundary: Angular unconformity (representing an erosional surface)
• Features in lower unit: Bedding planes, tilt
• Features in upper unit: Clasts (pebbles/cobbles), massive structure
• Scale: Geological hammer

b) Outline the geological features present:

• Angular Unconformity: This is the most prominent feature, representing a significant time gap where older, tilted sedimentary strata were eroded before the younger dolomitic conglomerate was deposited horizontally on top.
• Tilted Sedimentary Strata: The underlying rocks show clear bedding planes that are tilted, indicating past tectonic deformation (folding or tilting) before erosion.
• Dolomitic Conglomerate: The overlying rock unit is a coarse-grained sedimentary rock, suggesting deposition in a high-energy environment.
• Erosional Surface: The irregular contact between the two rock units is an ancient erosional surface.
