Abstract

Exposures of the Cedar Valley limestone adjacent to Iowa City show a wide variation from the conditions usually described for the disposition of limestones. Existing descriptions of the Cedar Valley limestone make little mention of the irregular lamination, the contemporaneous structures of the beds, the cross bedding, or the meaning of the lithographic zones in the formation. Such structures indicate a condition of very shallow regularly agitated water, with periods of actual exposure above water level.
