Budden Canyon Formation : ウィキペディア英語版 | Budden Canyon Formation
The Budden Canyon Formation is the name of a sedimentary rock formation of Cretaceous (Berriasian-Turonian) age.〔Murphy, M. A., Rodda, P. U., and Morton, D. M., 1969 "Geology of the Ono Quadrangle, Shasta and Tehema Counties California. California Division of Mines and Geology Bulletin 192, 28p.〕 The formation consists of more than 20,000 feet of clastic sediments of non-marine (alluvial fan), shallow marine, slope and basin floor fan turbidites. The formation is very fossiliferous with common macro-fossils, such as ammonites, gastropods, and bivalves found both in concretions and bedding planes, along with common petrified wood, woody material, and leaf and seed fossils. In addition to these are marine microfossils, including foraminifera and microgastropods. There are also rare vertebrate remains, including marine turtles. ==See also==
