Examine sample C. Sample C is a quartz sandstone with red claystone "rip-up" clasts. The red color in the mudstone is due to oxidation of iron in the mud. This implies a depositional setting (sedimentary environment) that was rich in free oxygen. Given that sand is deposited under moderately-energetic current conditions and clay is deposited in low-energy water (i. e., still water), then what does the presence of the claystone "rip-up" clasts surrounded by sandstone tell you about how water energy must have changed at this location when these sediments were deposited (i. e., before they were lithified to make sedimentary rock)
