Fracture Trace Analysis to Increase the Probability of Locating Groundwater for Murray County, Georgia

摘要

Fracture trace analysis was used to determine potential sites to drill for groundwater in the Appalachian Valley and Ridge Province of Murray County, Georgia. Aerial photographs, at a scale of 1:20,000, were analyzed stereoscopically to identify the fracture traces. Atlases were made of the seven major 7.5 minute quadrangles in Murray County showing where the fracture traces lie. Developed land and land leveled by flooding in the flood plains tended to obscure some fracture traces, whereas undeveloped land, which tended to be in rough terrain, better defined fracture traces. Location of the fracture traces was discussed in terms of the geology of the area. Recharge areas in Murray County were identified using stereoscopic analysis also.
