WebThe euhedral andradite–grossular crystals used in this study are dark brown to black in color, about 4 mm in diameter, and show low birefringence in cross-polarized light ( Figure 2 ). In plain-polarized light, lamellar features are observed [ Figure 2 (a) ]. The sample shows fine-scale tweed-like features [ Figure 2 (b) ]. Figure 2. WebSep 1, 2011 · Clinopyroxene is the dominant phase in nepheline diorites. Titanian garnet occurs as an uncommon accessory phase forming reddish to deep brown individual grains. Chemically it is intermediate between Ti-andradite (67 to 78 mole %) and grossular (21 to 33 mole %) with TiO2 contents ranging from 1.5 to 5.0 wt %.
