Summary:
Pg. 477-479. Ogden quartzite. Usually white or pale green, very fine-grained and slightly schistose toward top, and contains zones of conglomerate consisting of remarkably smooth quartz pebbles in a fine siliceous matrix. Thickness 1,000 to 1,600 feet. Named from development in Ogden Canyon, northeastern Utah. Overlain by Wasatch limestone (Carboniferous and Devonian, 7,000 feet thick) and underlain by Ute limestone, of Quebec [Ordovician] age. The Ogden is provisionally assigned to Devonian. In western Nevada it is 700 or 800 feet thick and is also seen to lie between upper and lower Helderberg [Devonian] horizons.
