Lithology Comments

Sep 15, 2015 (A Wilson) - The 16.7 m deep quarry exposes limestone and dolostone of the lower member of the Gull River Formation. The limestone beds are often mottled with dolomitized burrows or indistinct patches. Most of the limestone is light to dark grey, thin to medium bedded and microcrystalline. The medium-bedded, fine-crystalline dolostones usually weather a light brown or green and often contain vugs. Shale interbeds are present in the upper 10 m of the quarry.
