The J. T. Brand quarries include about eight openings on a 20 acre exposure of Lithonia gneiss located between Little Stone Mountain and Collinsville Mountain. A large amount of stone was removed from these quarries in the late nineteenth and early twentieth centuries mostly for Belgian blocks and curb stone.
The rock is typical highly contorted Lithonia gneiss with numerous garnet and magnetite crystals disseminated throughout. Shear zones, flow folds, and garnet-rich epidote-bearing layers are common in this exposure.
