content: OG-1 Ordovician Gasconade Chert: The ground is light gray to off-white. Zones of medium to dark gray bands (up to 10 mm wide) are adjacent to zones of wispy, thin gray lines. Crystal lined and filled vugs and seams are common. Texture is medium to coarse. The chert is often badly fractured (often healed). Knappability is poor to fair usually, but is good occasionally. This chert could be confused with Cotter dolomite Variety 3. However, this chert has a coarser texture than does Cotter Variety 3, especially in the light colored areas, and the latter often have irregular dark spots with white centers.
