ee) 
2. Metamorphosed siliceo-argillaceous slate—black ; minutely granular, with fine 
glistening points ; joimted; resembles some of the basaltic dikes. 
3. Clay-slate, much altered, but shows the laminar structure distinctly,—black ; 
no traces of a crystalline structure ; no glistening points as in No. 2. 
4. Siliceous slate—greenish gray; in near contact with the greenstone dike, is 
changed to a schistose quartz rock, which, in some of the layers, is granular. 
5. Greenstone, coarsely crystalline; weathered surface rough, iron-shot; colour, 
dark greenish gray. 
6. Quartzose sandstone—fine granular; colour, brick-red; resembles some of 
siliceous schists. 
7. Quartzose schist—greenish gray; granular in thin laminew; resembles the 
slaty greenstones of Kinuhigakwag Creek. Iron stains between ti laminee, and in 
the joints. Makes a near approach in some layers to hornblende slate. 
8. Clay slate, alternating with the quartzose layers. 
9. Hornblendic rock—bedded and jointed like the overlying schists; layers from 
an inch to an inch and a half thick. Colour, grayish black ; minutely crystalline. 
10. No. 9, passing into greenstone; more coarsely crystalline than No. 9; but 
evidently the same rock. Dark greenish gray; compact; weathers with a thin, 
grayish, iron-shot crust, nearly white externally, contains much yellow iron pyrites. 
11. Greenstone. 
12. Clay-slate—rusty surfaces between the joints; fracture smooth; lustre dull ; 
no glistening points; no appearance of crystallization. 
13. Hornblendic schist—fine grained; bluish green; light gray on exposed sur- 
faces ; dark brown in some places; irregularly laminated; in some spots rather 
compact. Intercalations, of a reddish-coloured jasperoidal rock. 
14. Granite—light-coloured, gray, mottled ; fine-grained; compact; gneissoid. 
15. Hornblendic rock—highly crystalline; green; resembles diallage rock. 
16. Same as No. 15. 
17. Hornblende rock—coarsely crystalline; dark-coloured, almost black. 
18. Slaty hornblende—with seams of iron ore. Some of the beds are siliceous, 
and resemble the quartzose schists, but are highly ferruginous. 
19. Quartz rock. 
20. Hornblendic rock—fine-grained ; grayish-coloured; resembles No. 16. 
21. Syenitic granite. 
22. Slaty hornblende—with intercalations of hornstone. 
23. Siliceous slate—chloritic. 
24. This rock is syenitic in the mass, and should be placed among the granitic 
rocks. It is composed of quartz and hornblende in about equal proportions. Some- 
what fine-grained. It merges into a hornblendic rock. 
25. Clay-slate. 
26. Syenite—passing into greenstone. 
27. Porphyritic greenstone. 
28. Hornblendic rock—dark-coloured ; fine-grained; patie 
29. Slaty greenstone—minutely crystalline.
