This is an image of rocks that I picked up from Ocmulgee National Monument. Most of the rocks were Granite rocks, consisting of Biotite, Quartz, and Feldspar. Two types of Feldspar can be identified, Potassium (Pink) and Plagioclase (White). I also found a few pieces of Scoria, which depicts some sort of volcanic activity with high volatile content. I wonder how the rock got there. It was near the railroad tracks.
