Place letters in order from youngest to oldest
Use the stratigraphic column presented below to answer questions 10 and 11 10) Our class goes on a field trip to observe four rock outcrops, which are located approximately 10 miles apart. At each outcrop, detailed not the rock type and fossil content of each rock layer. Additionally, samples a collected in order to compare the rocks from outcrop to outcrop are used to construct the four cross-sections shown below match and the collected rock samples es are taken on re . These data . Each unit with a ing letter has been correlated by using the data collected in the field . For example, all of the units labeled A have been identified as the same rock type and the same age. Place the units in order from youngest to oldest based on their positions in these four cross- sections. :Youngest 0 G. ·? Oldest Location Y Location Z Location X Location WExplanation / Answer
Youngest to oldest:
C, E, H, A, F, G, B, I D
These layers actually have multiple sequences- the C, E, H sequence actually is a new series. This layer is followed by the A and F layers. The G strata is actually an intrusion- probably a dyke that has intruded the D, I, B sequence.
