A rare metachert pebble containing amphibole grains with microboudin structures in a wide range of orientations provides an opportunity to perform stress analysis in two orthogonal orientations on the foliation surface. The sample was analysed by the microboudin method to infer the triaxial stress state during microboudinage. Stress parameters proportional to the far-field differential stress were determined for sodic amphibole grains in the two orientations. The ratio of the stresses in the two orthogonal orientations (σ 1 -σ 2) /(σ 1 -σ 3) was calculated to be 0.64, indicating that σ 2 lies closer to the midpoint between σ 1 and σ3 than to σ3.
