Two specimens of flint described by Green have been subjected to intensive x-ray fabric analysis. The specimen compressed in the β-quartz field recrystallized to a fabric with a strong maximum of c-axes parallel to the direction of compression and a weaker equatorial concentration perpendicular to the axis of compression. Annealing of a similar specimen eliminated the equatorial concentration and strengthened the axial concentration six- to eightfold. In the latter specimen, the fabric determined by x-ray analysis agrees closely with Green's optically measured fabric. It is possible to obtain c-axis fabrics directly from the very weak 0003 diffraction peak.
