The Glenray Limestone Member of Bluefield Group is also known as "Little Lime" by drillers. Lies 50 to 150 ft above the base of the Bluefield and directly above the Lillydale Shale Member. The limestone is medium-light gray, very fine grained, silty, dolomitic, micritic, and contains black chert nodules. Member is thin to thick bedded, ripple bedded and is interbedded with light-greenish-gray shale and siltstone containing abundant ARCHIMEDES sp. The Glenray varies between 10 and 80 ft in thickness. Underlies unnamed strata below the Indian Mills Sandstone Member that consists of fossiliferous, light-greenish-gray shale and limestone and grayish-red to greenish-gray, fine-grained sandstone. Age of the Glenray is Late Mississippian (Chesterian).
