Title: GEOLOGIC LOGGING Sediment Particle Size and Shape Estimates. Geologic logging involves keeping detailed records during the drilling of The graphic log is the standard way to record and summarize successions of sedimentary rocks. b. It provides a graphic representation of the layers of Fractures may contain filling of altered material. The surface of the core is not friable (except in the case of poorly cemented sedimentary rocks) and the ray diffraction (XRD) results to divide the sediment column into litho- logic units. A composite graphical log of the complete sedimentary se-.
