660 A. J. TIEJE 
Quartz rarely 0.06 mm., very angular. Plagioclase rare. Buio- 
tite bleached. 
Classed: micaceous-arenaceous shale. 
Wy 2: Same locality as Wy 16, 40 ft. above granite. 
Description of hand specimen: Sandstone, thin-bedded, alter- 
nating and interleaved with fissile green shales; now banded green 
and white, subsoft, micaceous, now reddish-green, medium-grained, 
calcareous. 
Texture granular-fragmental. Constituents quartz go per cent; 
glauconite 8 per cent; magnetite, ilmenite, calcite as accessories, 
limonite and leucoxene as alteration products. Cement calcite. 
Quartz averages 0.05 mm., angular; rare vein quartz. Glau- 
conite in aggregates (0.16 mm. diameter) oval to rounded, bordered 
and veined by limonite; no seeming relation to shell fragments. 
Classed: glauconitic superfine-grained sandstone. 
Wy 9: Same locality as Wy 16, 170 ft. above granite. 
Descripton of hand specimen: Glauconite sand, massive, 
emerald green, crumbling, coarse-grained, subvitreous luster. 
Texture granular-fragmental. Constituents glauconite 95 per 
cent; limonite as alteration product 5 per cent. Cement limonite. 
Various chitinous fragments and rods. 
Glauconite aggregates as in Wy 2, but fresher. 
Classed: glauconite sandrock. 
Wy 25: Same locality as Wy 27, approximately 30 ft. above 
granite. 
Description of hand specimen: Sandstone, massive, buff where 
fresh, weathering dark-red. Superhard, fine-grained, dull luster. 
Weathering exhibits buff nodules in relief. 
Texture granular-fragmental. Constituents quartz 85 per cent; 
small amounts of biotite, muscovite, glauconite, magnetite, ilmenite, 
plagioclase, microcline, zircon, apatite as accessories, and leucoxene, 
kaolin, limonite, sericite, chlorite, epidote as alteration products. 
Liquid and gas inclusions in quartz. Cement quartz and limonite. 
Quartz averages o.2mm., angular; fragments often elongate; 
one grain 0.6 by 0.35 mm; vein quartz rare. Plagioclase a mass
