Geology from the Airplane
Flying South over North Odgen Utah we admire the rock cliffs of the Wasatch Range. Prominent is the light gray band of tintic quartzite a 530 million year (Ma) old cambrian formation. Just below is the Farmington Canyon Canyon Complex (dark grey), a precambrian metamorphic deposit. This rock was metamorphosed about 2,6 billion years ago from protolithic crust between 2.8 and 3,6 billion years (2,800 to 3,600 Ma) old. The gap of about two billion years represents a substantial unconformity over nearly half the earth's existence with no apparent geological activity in this area.
These formations stretch along the Wasatch front for 30 miles or so. Sometimes the sequence is duplicated because of thrust faulting during the Sevier orogeny (100-80Ma ago).
