Archie Chapman quarry
The Archie Chapman quarry is located about one and one-half miles north of Lithonia, approximately 600 yards east of the Stone Mountain-Lithonia Highway. It contains two openings, the larger of which is 150 feet long, 100 feet wide and up to 15 feet deep.
The rock in the large quarry is a faintly banded, medium-grained, light gray biotite gneiss with numerous porphyroblasts of microcline and magnetite. The banding has a uniform strike of N15°E and ranges in dip from 15°-30°E.
The banding becomes progressively more deformed to the east, until it reaches the stage of typical highly sheared and contorted Lithonia gneiss in the eastern quarry. The trend of the banding in this quarry is very erratic, and the rock contains many randomly oriented pegmatite veins and dikes.
