WebJul 6, 2024 · Simple estimators were developed for the estimation of variably oriented fracture trace length as well as trace density. Reliability of results depend on the probability function assumed; underlying distribution of trace length is generally unknown. WS: Mauldon (1998) Probability analysis, numerical and analytical methods WebThe fracture trace analysis can identify faults, fractures, joints and veins within the underlying bedrock. The overall intent is to identify directional trends of sinkhole alignment. Upon completion of the fracture trace …

The purpose of the fracture … WebJan 1, 1994 · Lineanents and fracture traces have been mapped throughout Decatur County, Indiana. These lineaments and fracture traces may indicate that solution enlarged vertical fractures in the limestone and dolonite aquifers underlie most of the county. The use of lineament and fracture-trace maps in selecting bedrock-drilling sites results in a …
WebMar 27, 2024 · Photogeologic fracture trace and lineament mapping of the eastern portion of the Wartburg Basin, Tennessee provides important new data on the structural framework of the Cumberland Plateau and makes possible some correlation between remotely sensed linear fractures and bedrock structure. Fracture traces and lineaments are generally … WebDec 1, 2024 · Rapid collection of outcrop fracture trace map observations is an essential early step in fracture analysis protocols to predict permeability and strength. Current mapping protocols use a scale-invariant method that implies that intersection relationships (I-, Y, and X-nodes) are the same at all scales (e.g., Sanderson and Nixon, 2015 ) but ...
