Construct a restored section for these Devonian rocks in Figure 7.5 similar to the example in Figure 7.4. This exercise is just a large-scale version of what you did with two or three stratigraphic columns in lab 4. Start by placing the stratigraphic columns side-by-side to create a complete transect of sections. With solid lines, dashed lines, and pinch-out symbols, connect the various lithologic units. Color each lithology a distinct color, and create a legend on the backside of Figure 7.5. Neatness counts. Exercise 2: Answer the following questions as you interpret your completed correlation. Does Walther's Law apply to these rocks? Are there exceptions? Give specific examples from your columns. 2. Are all of the conglomerates the same age? No, fossil evidence Shows that they range 3. What trend is visible in the sandstone beds as they are traced from east to west? From east to west, the Sand Stone thins and is Separated by shale. 4. Why do the shale beds thin as traced from west to east? less Shale is deposited Closer to Shore. 5 What happens to the sandstone bed near the base of sections 13-15 in section 12? What is suggested by the small lens of conglomerate near the top of section 3 in the time interval between f and g? Tr age
