26 A unified system of collecting structural data from drill core is proposed. The system encompasses 27 planes and planar fabrics, lineations, fold hinges and hinge surfaces, faults and shear zones, 28 vorticity vectors, shear directions and shear senses. The system is based on standard measurements 29 of angles in the reference frame of the core (α and β angles), which are easily carried out by means 30 of core protractors or templates. The methods for dealing with folds and kinematic
