Kansas City is a Late Carboniferous geologic group and formation having various significant alternating beds of limestone and shale known for forming high bluffs in Missouri, Kansas, and neighboring states. This formation was named for the bluffs within Kansas City, Missouri.[3] Primary group outcrops are in northwest Missouri. This group has been a historic oil producing unit within the state of Kansas.[4]
