Occasional references have been made in geological literature to the brecciation which marks certain zones of the Cedar Valley limestone of eastern Iowa. Additional data is presented in this paper on this subject. A new type of structure which appears as slickensides and grooves is described and interpreted as the result of movement prior to complete hardening of the lime ooze. There is a suggestion that this movement may be partially responsible for the formation of the stylolites which also occur in the same bed.
