A. Stereographic projection of the optical directions, X, Y, Z, and the reciprocal lattice vectors, a*, b*, c* (where b* and b coincide for the monoclinic case), based on the S and E values given in Table 4 for dickthomssenite. To determine the optical orientation, a and c are also added to the projection (see text for details). Based on the projection, Z = b and X:a = 16.5°. B. The direct crystallographic axes and X, Y, Z have been rotated to the standard position for monoclinic minerals, with c vertical and b on the right of the projection. After these are rotated, it is easier to view the optical orientation.
