The Genoa Quarry is an active quarry for building stone and aggregate located in the W 1/2 of Section 3, Genoa, Clay Township, Ottawa County. The rocks exposed in the quarry are identified as part of the Lockport Dolomite.

Edward Orton (1888, p. 732) was the first geologist to describe the geology and quarrying of limestone at Genoa. Orton observed that there were three quarries with multiple kilns in the immediate area: Wyman, Gregg & Co. and A.L. Newman both owned three kilns each and William Habbeler had two kilns. These quarries were shallow with the deepest quarry only being 20 feet.

Carlson (1990, p. 524, 1991, p. 98, 2015, p. 166) noted in that Orton (1888, p. 735) had reported that the mineral baryte (which was often referred to as heavy spar) had been encountered at Genoa or from a subsequent abandoned pit nearby. (Carlson, 1990, p. 524). A further analysis of the literature reveals that although Orton had indeed misidentified the mineral celestine for baryte, which is commonly encountered at the Genoa Quarry, the locality that Orton mentions in his report that the “heavy spar” was found was at Clay Center and not Genoa.

In 1915, the United States Gypsum Company purchased 25 acres of land at Genoa with the prospect of getting into the lime industry. Rock Products and Building Materials (1915, p. 42) magazine reported:

The new constructed lime plant consists of nine kilns, a hydrator, automatic sacking machines and other machinery used in hydrating plants. Three additional units of nine kilns each will be added to the plant from time to time as the demand for product requires. The plant is built of concrete and steel throughout. The machinery is electrically driven with individual motors.

The method of getting the rock from the quarry to the kilns differs from the usual practice in this locality, in that instead of the long incline from the top of the kilns to the bottom of the quarry, the rock is hoisted direct from the quarry and dropped into the top of the kilns by a large traveling “Gantry” crane. This crane is also to be utilized in unloading coal and placing it through proper chutes on the kiln floors for burning the lime. The plant was completed and placed in operation on Dec. 1.

A crushed rock plant is now being built for crushing various size rock for road-making and ballast work.


By the early 1990s, the quarry began operations under the GenLime Group L.P. Company from U.S. Gypsum and in 1998, Graymont Dolime (OH) Inc., a subsidiary of Graymont acquired both the Bellefonte Lime Co. in Pennsylvania and the GenLime Group L.P. of Genoa. The quarry is still owned and operated by Graymont today.

ID: 2720013
Lockport Dolomite

Age: Silurian (423 - 443.8 Ma)

Stratigraphic Name: Lockport Dolomite

Description: Dolomite, shades of white to medium gray, medium to massive bedded, fine to coarse crystalline; fossiliferous; vuggy.

Comments: Secondary unit description from USGS Lexicon website (ref. OH017) and OH005:Rock units forming the bedrock in the Maumee, Lucas Co., OH, and that crop out in the walls of a quarry are the Lockport Dolomite and the Greenfield Dolomite. The two form a thick reef complex roughly 600 m in diameter and about 68 m thick. The Lockport contains multistory stromatolite, thrombolite, and coral-microbialite reefs that were probably formed in a subtidal setting within a hypersaline lagoon. Lockport may be Wenlockian or Llandoverian to Ludlovian. In contrast to the mostly massive Lockport, the Greenfield at Maumee quarry is well bedded. It is Wenlockian, according to Shaver (1991), but fig. 16 of this report (after Howell, 1993) depicts the Greenfield as Llandoverian with a significant hiatus between deposition of the two units (Kahle, 1994).
