Part B: Regional Geologic History<br />

Based on your observations, determine the stratigraphy of your units (the relative order of units from<br />

youngest to oldest). List the units in the column ÒGeologic UnitÓ in Figure 17.4 in order from youngest at the<br />

top to oldest at the bottom. Place an structural information in the column ÒStructural EventsÓ. Using the stratigraphic<br />

relations and interpretations based on your examination of the photomosaic, derive a geologic history<br />

for the Memnonia region.<br />
