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 movement.

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.
