content: Cedarville-Guelph Chert, also known as Logan County, Logan County Flint, and Shawnee, as an off-white to dark gray chert. When weathered it becomes off-white, yellow, tan, brown, gray, blue-gray, pink, or red. Possibly the same colors as weathered specimens when heat-treated. There are trace amounts of pyrite, chalcedony, and euhedral (a crystal completely bounded by its own regualarly developed crystal faces). It has a vitreous to earthy texture. Deposits include nodular in lenticular layers, interbedded with light gray, and medium-grained fossiliferous dolomite.
