All figures represent projections of the lower hemisphere upon a schmidt net. Fig. 8.—Positions of maxima A, B, G, X for quartz in No. 4457, as deduced from curves of Fig. 6 (cf. Turner, 1938; Fig. 9). Inset circle shows outline of vein with reference to schistosity. Fig. 9.—Fabric diagram for quartz (100 grains) in veinlets cutting schist No. 4457. Contours 8, 6, 4, 1%: maximum concentration 11% of quartz axes per 1% area. Measurements by Dr. E. Ingerson. Fig. 10.—Positions of maxima D, E, H, J for quartz in veins in schist No. 4487 as deduced from curves of Fig. 7 (cf. Turner, 1938a, Fig. 7). Fig. 11.—Fabric diagram for quartz (400 grains) in three parallel veins in ac section of schist No. 4487. Contours 3.5, 2.5, 1.5, 0.25%; maximum concentration 4% of quartz axes per 1% area. Fig. 12.—Fabric diagram for quartz (200 grains) in one vein in ac section of schist No. 4487. Contours 3, 2, 0.5%; maximum concentration 4% of quartz axes per 1% area. The measurements upon which Fig. 12 is based are included with 200 additional measurements in the data for Fig. 11.
