The rock found here is a porphoblastic granite gneiss and is part of the Corbin Gneiss Complex. These rocks are some of the oldest in Georgia dating back some 1.2 billion years, making it much older than the limestone at their Kennesaw location. This quarry is known for the blue quartz found within the granite.

The Quarry began operations in 1995 at this location. They have 797 acres and their pit is approximately 1,200 feet wide and 250 feet deep at this time.
