Geology Question - Determine the order of geologic events shown in this cross section of the Grand Canyon?
Deposition and metamorphism of Vishnu Schist Intrusion of Zoroaster Granite Erosion, creating unconformity S Deposition of Gravel M, Bass Dolomite, Hakatai Shale, Shinumo Quartzite, Dox Sandstone, Chuar Shales, and Nankoweap Group Deposition of Gravel M, Bass Dolomite, Hakatai Shale, Shinumo Quartzite, Dox Sandstone, Chuar Shales, and Nankoweap Group Deposition of Gravel M, Bass Dolomite, Hakatai Shale, Shinumo Quartzite, Dox Sandstone, Chuar Shales, and Nankoweap Group Intrusion of sill F (assume the words igneous sill were horizontal when intrusion occurred) Regional tilting Deposition of Tapeats Sandstone, Bright Angel Shale, and Muav Limestone Erosion of the Grand Canyon by the Colorado River Looks like Dead fuzz beat me by 20 seconds but he is correct also
Oldest to youngest: Deposition and metamorphism of Vishnu Schist Intrusion of Zoroaster Granite Erosion, creating unconformity S Deposition of Gravel M, Bass Dolomite, Hakatai Shale, Shinumo Quartzite, Dox Sandstone, Chuar Shales, and Nankoweap Group Intrusion of sill F (assume the words igneous sill were horizontal when intrusion occurred) Regional tilting Erosion, creating unconformity R (assume a horizontal erosion surface) Deposition of Tapeats Sandstone, Bright Angel Shale, and Muav Limestone Erosion of the Grand Canyon by the Colorado River.
