Abstract

A commercial engraving tool can be used to carefully disaggregate and vibrate matrix and cement away from stones in semiconsolidated diamictite core. Stone fabrics and planar structures in the core can be measured using a transparent protractor placed over a parallel-lined transparent template that is aligned with an arbitrary North line on the core to determine trends and strikes. Plunges and dips can be read using the dip needle of a geologic compass. These data, combined with stone surface features, shape, and provenance, allow interpretation of sediment genesis and processes where outcrops are rare or of poor quality.
