A quarry for building stone in the Lockport Dolomite and Greenfield Dolomite. The quarry is located in section 11, SW ¼ in Perrysburg Township. Most of the quarry is now flooded (beginning in 2010) and abandoned.

In 2003, Stoneco’s Ohio quarries became part of Shelley Materials, Incorporated. Ernest Carlson (2015) lists the Lime City Quarry as the Shelley Materials, Inc., Lime City Quarry (formerly Stoneco and Maumee Stone Co.).

Wenlock - Llandovery
427.4 - 443.8 Ma

ID: 2950656
Tymochtee and Greenfield Formations, Undivided

Age: Silurian (427.4 - 443.8 Ma)

Stratigraphic Name: Tymochtee Formation; Greenfield Formation

Description: Dolomite, olive-gray to yellowish- brown, thin to massive bedded, upper two-thirds commonly contains brownish-black to gray shale laminae; locally developed brecciated zones in lower one third.

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).
