PLATE 20.-Fig. 1.-Slightly crushed charnockite. Note the linear arrangement

of the various minerals. Fig. 2. -The centre shows one of the felspathic patches in Fig. 1

under crossed nicols. The granulation and disconti. nuity of the twinning planes is due to crushing and move

ment. Fig. 3.-Charnockite similar to that shown in Fig. 1, but more

intensely crushed. Most of the hypersthene is altered to

a feathery aggregate of scaly hornblende. Fig. 4.—Completely crushed charnockite, consisting of narrow bands

of hornblende (dark), felspar, etc. (light) and garnet (G). A few crystals of hypersthene (H) always seem to have

survived the crushing. PLATE 21.–Fig. 1.- Typical hypersthene-gneiss.
