Granite, limestone, and marble building stones are found in a 20-block area that is centered around the beginning of Peachtree Street. These three commercial types encompass a much greater range of rocks. Granite, limestone, marble, travertine, dolomite, serpentine, larvakite, gabbro, and gneiss are among the rock types found within the 50 varieties of commercial building stones used in the area. A map has been prepared of the area and specific sites of geological interest have been identified. The building name is given in the descriptions of the buildings and rocks found in the area so that they may be located easily. Only the three commercial rocks names will be used in the tour so that one can look at the rock samples and try to determine their true nature. The tour originates at Georgia State University, 33 Gilmer Street, Atlanta, GA. Walking tour created by Dr. Bob Power, former GSU professor in Geosciences. Revised by Dr. Hassan Ali Babaie, GSU Associate Professor of Geosciences.
