Geology of Colorado (Boulder Valley) - Field Trip #1, Stop #5: Lykins, Canyon Spring, Morrison, Dakota Formations

Prev | Index For This Date | Next
Morrison formation: cross-laminations in channel complex (clays & muds). Overall, the Morrison formation consists of clays, siltstones, and carbonates (e.g. gypsum) which accumulated in a warm, moist lowland environment. Sluggish rivers were responsible for the deposit of mud and silt, which hardened into shale and siltstone respectively. Gypsum forms from the evaporation of a warm shallow sea.
