OSXBackstrip performs 1D Backstripping of sedimentary Strata. Backstripping is not a difficult task but is tedious. OSXBackstrip makes backstripping easy.
OSXGeoCalc is a Structural Geology calculator. It operates on lines and planes, strains, stresses, and oriented drillcore data. Individual computations can be made using the calculator's interface. Multiple computations can be performed using text files. Lines and planes can be visualized in a stereonet. Stress and strain operations can be visualized in a Mohr diagram.
