Problem:
The storm-disrupted layer identified in this model at annotation #1 contains abundant fossils (bioclasts) as evidence of storm wave action. The layers above that storm layer do not contain any clasts to indicate wave action. What can you conclude about these layers in terms of whether they were deposited in calmer water with little to no wave energy or deposited in high wave energy water? Need Assignment Help? View Available Hint(s)for Part A The fine-grained sediment and horizontal bedding indicate water flowing at a constant, low velocity in one consistent direction. The layers contain no fossils because the calcite was inorganically precipitated, so there is no indication of wave energy. The fine-grained layers were lithified to solid rock before the next layer was deposited, so storms and wave action could not affect them. The layers above the storm layers have horizontal and parallel bedding surfaces that were not disrupted by any kind of activity.
