Slightly sericitized sodic plag and orthoclase are the feldspars. A few small grains of quartz are present. Biotite, the more abundant mafic, contains numerous magnetite inclusions. Hornblende, mottled brown with some green, includes magnetite and apatite. Sphene and pyrite (cheifly included in large magnetites) are the other accessories. |
