Abstract

A unified system of collecting structural data from drill core is proposed. The system encompasses planes and planar fabrics, lineations, fold hinges and hinge surfaces, faults and shear zones, vorticity vectors, shear directions and shear senses. The system is based on standard measurements of angles in the reference frame of the core (α and β angles), which are easily carried out by means of core protractors or templates. The methods for dealing with folds and kinematic analysis of shear zones have not been described previously, but they follow logically from the standard methods for dealing with planes and lines.
