116 ART. 2. — B. KOTÔ: 



The fourth is a psammitic quatiz-schist slightly tinged with 

 yellow. 



The last is a phyllitic foliaceous seiiclte-sehist, and is a 

 modification of the second. The flecks are produced by the 

 accumulation of graphite. Tlie general mass is made up of 

 quartz grains of honey-comb structure. A few tourmaline rods 

 are present as an accessory. 



These schists make multifarious alternations witli the strike 

 N. 60^ E., and the dip 70' N.W., well exposed at the old castle. 



At the west of the town, members of the same schistose 

 series, but of different petrographical characters, are exposed, 

 keeping the same strike and dip. The prevalent rock is a white, 

 sericitic " Lagengneiss ", consisting of quartz-orthoclase aggregate 

 with hornfels- structure. A rather large microcline contains quartz 

 grains in the poikilitic fashion. Sericite occurs in thin lamiutne. 

 The strike is N. 60" E., and the dip 80 N.W. 



Intercalated with the above, there occurs cpidote-liornUeiide- 

 gneiss having a microtexture of the so-called Lagen and woody 

 forms, both combined. Individual grains are aggregated so as to 

 produce the hornfels -structure. Components are grains of quartz 

 and a few feldspars in small quantities, besides needles and lashes 

 of grass-green hornblende. Drop-like titanite and epidote grains 

 are also present. The rock is the injected apophyses sheared 

 subsequently to the present form. 



The complex is warped up at the north end with the contrary 

 dip, thus producing a syncline on the base of a biotite-granite.
