Figure F16. Photomicrograph in cross-polarized light of two types of exsolution textures in augite (Sample 176-735B-138R-7, 0-4 cm). On the left, the augite has abundant fine-scale, planar exsolution; on the right, the augite has course tabular exsolution. Both textures are formed by the exsolution of low-Ca pyroxene in an augite host. Field of view = 2.8 mm.
