Martin Marietta Cedar Rapids Quarry
An aggregates quarry operated by Martin Marietta (2026). It is located at 1636 Marietta Road, Ely, Iowa, 52227. It is just west of Palisades Kepler State Park.
Deposit: The plum creek fault zone lies just north of the quarry. Two sets of vertical joints are present; N 77 w, and N 35 e. Cadastral location: NE 1/4 sec. 15, t. 82 n., r. 6 w. ; info.src : cobb
Geology: Mineralization was confined to solution enlarged vertical fissures and cavities in wall rock - late silurian dolomite (scotch grove and gower formations); colloform banded sphalerite, marcasite, and orange calcite of typical upper mississippi valley district habit are abundant. Fluid inclusions indicate a temperature range of 69-99 c.
Rock formation(s): Scotch Grove
