YiG. 1. — Section from Serigasawa to Miharn, tlie latter beiug the well-known town 

 in the Abnkuma plateau. It exhibits the complicated mode of arrange- 

 ment of granites. (See p. 219.) 



gnBG, — schistose biotite-granite ; I gnG,— schistose hornblende-granite.

Fig. 2 and 3. — Cuttings along the newly opened road west of Tamano-yu, Naraha 

 göri, Iwaki, showing the relations of granites and dyke-rocks. (See 

 p. 276.) 



HG, — hornblende-granite : 

 BG, — biotite-granite ; 



Peg, — pegmatophyre-dykes ; 

 Lamprophyre, — diorite-porphyrite. 



Fig. 4. — Section J-K, from Kami-Matsukawa in north-easterly direction to the 

 district-boundary of Ishikawa and Shirakawa, illustrating very clearly the 

 relations of the ïakanuki series, granites, and serpentine. 



gnG,— schistose hornblende-granite ; 

 HG.^hornblende-granite ; 

 BG, — biotite-granite ; 



UT,— Upper Takanuki ; 

 LT, — Lower Takanuki ; 

 S, — serpentine. 



Fig. 5. — Section near Shimo-Kawabe, showing the relation of schistose hornblende- 

 granite and fleams of the Takanuki gneiss. The whole is traversed by a 

 pegmatitic dyke. (See p. 218.) 



Fig. G. — ^Cutting between Tonda and Higashino, exhibiting black, attenuated patches 

 of the dioritic composition Avithin hornblende-granite, which arise from 

 chemical differentiation of its granitic magma. (See p. 216.) 



Fig. 7. — Section near Ötsuka, as exposed on road side, bringing to view a gradua- 

 transition of hornblende-granite to its schistose variety within the amphil 

 bolite series of the Upper Takanuki. (_See p. 214.) 



A, — gneiss-mica-schist ; I B, — titanite-auiphibolite ; 



gnG, — schistose-granite ; I HG, — normal hornblende-granite. 



Fig. 8. — Small belt of the Gozaisho rocks pinched in between granites. (See 

 p. 212.) 



BG, — biotite-granite ; 



b, — salite-hornblende-schist ; 



d, — amphibole-picrite ; 

 gn, — schistose hornblende-granite. 



a, — epidote-amphibole slate ;
