Elliott, William S. 1 1 Dept. of Environmental Studies, Southern Oregon University, Ashland,   The Hornbrook Formation is a Cretaceous overlap assemblage that rests unconform-ably on accreted terranes and plutons of the Klamath Mountains in southern Oregon and northern California.

The combined results of sandstone petrography, detrital zircon U-Pb age and Hf isotopic systematics, and whole-rock Nd analysis document an abrupt change   The Upper Cretaceous Hornbrook Formation is mostly a marine sequence conglomerate, sandstone, and mudrock deposited in a forearc basin.
