Question
Using the diagram below - list the relative ages of all of the geologic events illustrated below, in order from oldest to youngest. Note that letters represent sedimentary rock units, igneous intrusions, and faults. (Write the letter of each unit into the answer boxes, not the rock name - those are just given to help you interpret the picture. In other words, no single answer should be more than one letter long)
[KEY TO ROCK UNITS: A=granite, B=siltstone, D=sandstone, E=granite, F=shale, G=limestone, H=gravel, J, L=shale, M=basalt, O=sandstone, R=sand, S=gabbro, V=gneiss, X=shale, Z=conglomerate]
JG A o K D E BExplanation / Answer
oldest to youngest sequence is A , V. O , X, B , J, G,M,S,Z, C, K , E
WHERE
A=granite, B=siltstone, D=sandstone, E=granite, F=shale, G=limestone, H=gravel, J, L=shale, M=basalt, O=sandstone, R=sand, S=gabbro, V=gneiss, X=shale, Z=conglomerate]
