Abstract

An interesting relationship between the beds of limestone and dolomite in a quarry and at outcrops along the Des Moines River near Rutland, Iowa, is described. In the quarry a composite of 11 feet of limestone-dolomite-limestone is exposed, whereas at an outcrop along the river 300 feet northeast the dolomite is absent and 12 feet of limestone is exposed. These beds of limestone and dolomite have been referred to the St. Louis formation uncomformably overlying Gilmore City limestone. The author proposes that the dolomite represents an area of late diagenetic alteration within the Gilmore City formation.
